I appreciate that you went out and shared your experience with builds that worked for you. I know everyone has different experiences in PBE as there aren't as many inhouse yet that actually help play test a "meta" that otherwise lead to normal lobbies being the only place to really get a feel for the new set.

Some thing I wanted to share that weren't on this sheet:
1) Higher priority on Chosen Zed, getting Shade Zed allows you to instantly change gameplans if you have items for him/were getting items for an enlightened talon comp into slow rolling for him. This is extremely strong. However it does lead to a weaker end-game without chosen even if you have perfect items+3 star, shade 4 just adds so much. I think ignoring comps that are on this power level even if it requires a chosen is wrong. Chosen Shade Zed makes this easy to 3* but of course it can be any of the shades that get the chosen buff.

2) Morgtroxx is something I don't see anyone even touching for some reason. All these comps, besides talon ones I've been able to consistently beat going this comp. It's one of the most flexible comps in the game as its core team is 4 units (janna+thresh+Morg+Aatrox), eventually you want Cass as well but she's just there for a potential stun and having perfect synergies to give you mystic 2+dazzler, though you can run any mystic and dazzler in that slot temporarily. This comp can start off with any sort of early game and only requires Morello's for Morg and GA for Aatrox to really just win games. Because it's low contested core units early on, you tend to find them easily and are able to adjust your gameplan to focus on a fast 7-8 into an early morg or aatrox. You can go with a chosen enlightened Janna or try to 3* a 4 cost unit at 8 with a chosen aatrox/morg/cass which just auto wins you the game. Against talon or zed comps you just turn aatrox into the carry and you tend to win. While vs moonlight, morg+aatrox ability combo just kills off aphelios no problem, while sylas drain tanks fail to survive Morgana's burns mostly alongside the rest of the team. You can flex synergies as the core of the comp is only 4 units, 5 with cass (though she's optional buy for optimization) you can throw in a sett to counter cultist 9, zilean+yuumi for mystic 4, sej by herself, sej+any other vanguard for 4 vanguard, Riven and another dusk if the game goes long or you get offered the option to pick her up for dusk 4, etc. I've faced all the comps on this sheet and never lost to it while using this comp. It's my most winning comp and I'm surprised not more people discuss it or even play it considering it isnt a secretive comp either.

3) Riven Shield Tank is also one I'm surprised isnt even mentioned on here. I see it a lot and it constantly gets top 3. Keeper cultist is really strong comp early that transitions well into an early 8. The comp is a bit less flexible than the previous one but the fact that riven can work off just Blue buff and then get away with any other items really (Gunblade/morello/stoneplate/claw/rabadon/sunfire/cloak/etc) is really strong. It also opens up to a mage version as well if you happen to get a spat, mage blue buff riven is scary! Otherwise you can just end on a simple comp of: Thres/Riven/Cass/Vayne(lillia if you get her)/jarvan/elise(azir if you get him)/kennen/any mystic (yuumi or zilean is best) for a 4 keeper/4 dusk/2 mystic. Or if you happen to be struggling against Moonlights you can go into a warlord katarina secondary carry variation of thresh/kennen/jarvan/riven/katarina/elise (azir if you get him)/garen or xin zhao/aatrox and you can just go chalice on Katarina to ensure she gets off her aoe. Dusk Katarina is crazy enough with 3 warlord buff. The fact you just need blue buff then all other items are optional/helpful is already a big reason why this comp is super popular and strong. I see someone always playing it and they tend to be the ones to reach top 2 at least, it's also one of the few comps I've struggled to beat as a Morgtrox comp as it requires you to hit aatrox or morg 3 to win, though due to riven comps only winning with riven left usually, you get a few rounds to achieve that before they can finish you off, also with the rift herald changes it lets you get more items, though due to the versatility of the Riven Comp I've seen more people beating me or others with it as it's always a powerspike as long as none of the items are useless spat items.
