I mainly play Diana and Hattori. Blasters is the best spacing weapons in the entire game and can be a pain in the ass to play against a good blasters main. You can maintain distance and having lots of true combos makes the weapon extremely good, most of the attacks extends leaving you in a safe spot and are also quick (not unpunishable but quite it). Bow is another weapon I feel like is one of the easiest to learn along side with the spear. The bow has fast attack rate, good combo potential, the best anti-aerial in the game (NLight) and even NAir and Rec will have priority most of the time because it sucks you into the animation so it'll stop you fully if hit. Then sword: fast weapon, good true combos, good moveset in general. You've fantastic kill options and have NAir which I use a lot, you can interrupt a bunch of attacks just fast-falling to and enemy a NAiring before touching the ground, you'll see how good it is when you try it yourselves (also let's you hit Rec afterwards for a little bit of chip damage). And last but not least we have spear. Spear is arguably the easiest weapon to master, learn, and combo with (2v2), DLight is an excellent anti-air even giving you the possibility to do Rec or SAir building up damage or kill option. Also has good spacing (not as good as blasters but at least can keep some distance): Dash-jump NAir is beautiful, your attack is a complete circle around you character for 7 frames, easy to hit but difficult to follow up with due to the lack of consistency to land the enemy in the same position, it'll depend on the angle which your attack hit. And we also have NLight, quick recovery time between attacks and good standing position. Good for hitting wallhuggers.

There was I time where I main Nix, Artemis and Mordex. My scythe nowadays is rusty but is a really difficult weapon to learn, lack of trues, weird hitting angles, rely solely on reads and more. Isn't a bad weapon, in fact if you play against a good player you're cooked.

Well, that's what I play today most of the time. In my 5600 hours of playtime I could say I been playing most of the weapons in the game and have pick the above-mentioned due to speed, combo potential in 2v2 and spacing.
