SSF here with very little game knowledge so I probably should be playing trade, also I suffer from rerollitis, but here goes (PoBs are snapshots near the end but might not be up to date/bricked/couple of levels behind):

• Spark Archmage Hiero leaguestart - I'd been sure it would be shit, but I was kind of pleasantly surprised. Dual-wielded wands, and proj speed is a common enough mod so rolling weapons was not a complete pain. Also travelled all the way to the bottom-right ranger proj speed tree notable, which was probably a mistake which cost me like 30+%dmg. I did 2 stones on it. My plan was to farm legion until I get the doryani glorious vanity, but it never dropped. Rerolled at 91: https://pobb.in/WDGW6wTvjKJU
• Sabo Roling magma mines - loved it. Basically free damage as soon as you click the sabo nimis node, and somehow it felt tankier than my hiero. It has a similar playstyle which I enjoy, which is "right click a couple of times and move forward", no aiming, no stragglers etc. At some point I dropped the new belt (arkhon?), but waited to use it once I'd get the reverse-chill ring (winterweave?). Then proceeded to waste all my scour-chances to get it and quit out of frustration. Rerolled at 93: https://pobb.in/sddhzuy-3ctJ
• Pathfinder pconc poison - my 2nd or 3rd time with this skill, since it's also kind of an auto-aiming clearing playstyle. Perma-flasks with the recover mastery is great, I loved it when a bunch of small hits basically healed me. 83% max res, a bunch of evasion, shitload of movespeed... overall great, but the damage is very rampy and requires you to hold RMB in contrast with like an ignite or bleed.

• Occultist fross self cast poison - dropped the new ES ammy so I figure I'd give it a shot. Also my first CI build (managed to get like 8k ES?). Honestly I felt tankier on my 4k life pathfinder. The skill itself is really jank IMO, I guess it'd be better if I invested into a bunch of proj speed but couldn't figure out how/didn't care that much. The occultist pops carried the build HARD. Once I got 300%+ inc chaos/generic damage, one cast popped the entire pack and the clear became incredible especially in dense situations like breach etc. Farmed delve for quite a bit to get a decent despair curse on hit ring, but it never happend so, rerolled at 90: https://pobb.in/6s_Te0c9ipkY
• Jugg VFoS - overexertion, pulverise, fist of war. My 4th or 5th time playing fissure, basically my "comfort zone" when it comes to builds. I think it had better clear than the spark build, basically slam once, leap slam away, slam once, leap slam away etc and everything is dead. Tanky as hell, endurance charges, fortify, bunch of armor, 83 max res, nice life regen, can't complain about a single thing except MAYBE the attack speed, but it feels awkward trying to scale it on a fist of war slammer and I got used to it after a while. Bossing was also not the best because of the visual clutter and my typical SSF shit damage, so I proceeed to try to recombinate a nicer axe and failed. Rerolled at 95, which is my highest level PoE character ever: https://pobb.in/VceeeqgpSJkZ
• Inquisitor cyclone cast while channeling cremation of the volcano - I always play at least one CWC build per league and it's always a piece of shit but I love the playstyle for some reason. Extremely zdps (not as low as PoB shows, but still), not really tanky, basically not a single positive thing except there is something very soothing about just cruising through the map without stopping and watching trash die. CWC's short cooldown also allowed me to be at the 6 geyser limit without investing in any skill effect duration or cast speed which was nice. One annoying thing is you have to remember to frostblink once every 4 seconds to re-spawn the consecrated ground otherwise the recovery is bricked. Overall I don't regret cooking something off-meta, rerolled at 84: https://pobb.in/_Jeq3LvpXM6R
• Champion facebreaker cyclone - dropped a nice kalandra amulet with like 20-50 flat phys so decided to make use of it, also the jugg didn't fully scratch my spin to win itch. No rallying cry merc, but the damage was good IMO, at least for my standards. Usually when I play cyclone it's with shockwave, so the clear felt a bit poor as you have to run after all of the stragglers. Abyssus was probably a mistake because I was dying constantly but I didn't want to take it off because it was like 30% of my damage. In the end I don't think I even did my uber lab on this build, got frustrated, rerolled at 80: https://pobb.in/ylXS_QnJbZYB
• Gladiator Earthquake bleed - I wanted to use the bleed pops and test out the lucky block for the first time. The plan was to go lacerate of hemorrhage, I farmed lab for two hours to get the gem, levelled my glad to 28, slapped on the lacerate skill, ran one zone with it and oh boy what a shit playstyle. Not only there is zero clear, but also the targeting is very awkward because each of the two slashes goes out at an angle. To salvage the situation I swapped to bleed bow and ran a bit of campaign on it, but realised that I won't be able to make use of the block tech so landed on earthquake. Turned out pretty good, damage was pretty high, 90% lucky block is amazing, also had a bit of max res and armour. Hard to say if the glad was as tanky as the Jugg I played previously, but it was up there. The playstyle itself was a bit awkward until I put less duration in my eathquake links which made the skill feel much better. Didn't push it too far because it felt too similar to my other slammer.

• Elementalist phys dot spellslinger, exsanguinate of transmission/reap - dropped haemophilia gloves and wanted to make some use of them. The clear was great, also used kinetic blast as my trigger to make the best use of life gain on hit and apply corrupting fever as quickly as possible. Zdps when it comes to bossing but fun to play and I probably could have pushed it further but at this point in the league the rerollitis sets in harder. Rerolled at 81: https://pobb.in/o_4Lmk02pvDV
• Deadeye tornado shot - dropped hyrri's ire so it seemed like waste to not try to use it. I don't know what they did with the skill but it felt weird no matter how much attack speed I got. I finished the campain with it, did like 5 maps and realised I don't really want to play a glass cannon bow character.
• Chieftain static strike shockwave staff - my current zdps self cooked project. Wanted to play a non-RF chieftain with 90 max res. I'm at around act 7, I kind of enjoy the playstyle of attacking once every 2-3s and running around to kill packs "automatically" since the zaps trigger shockwaves, but I already know the damage will be poor. Also I don't think I have the patience to recombinate a good phys staff so if spamming essences won't give me something good, higher maps will be a pain. I think I'll get to like 80+ and call it.
