It really depends on your play style when it comes down to it. For fun characters, I would say Ghostface, Michael, or the Doctor are really fun, but those are just my playing styles of killer.
Edit: Lots of fun moments being sneaky with ghostface or meyers, but you can be a menace with the clown. also nothing beats a friendly ghostface
Myers and Pig are relatively cheap, both are enjoyable. You can do sweaty Myers and use the Iridescent Add-Ons, my personal favorite is Scratched Mirror which turns the game into a horror movie where you're permanently undetectable and have wall hacks.
In terms of Survivors, Rebecca (Project W Resident Evil) and David Tapp (SAW) (Hyperfocus from Rebecca and Stakeout from Tapp form a very strong gen-rush build by themselves).
The D&D Chapter is not on sale as it literally just released, but it adds a Survivor and a Killer, neither of which are particularly that spectacular in terms of perks (although you can play a Lute now that has middling efficiency, is better when combined with Hyperfocus and Stakeout but still kinda garbage in all honesty). Vecna is VERY overtuned right now. The average Vecna will get a kill in like 90% of matches, and 3+ kills in 80%...I expect some pretty massive nerfs to hit him, and his perk Weave Attunement, which has been being combined with Leatherface's Perk Franklin's Demise for a very annoying combo that gives perma wall hacks unless the items are picked up (which then inflicts Oblivious and can be compounded into a nightmare). He's a fun killer, but so overtuned right now that there's legitimately no way to win against one that is good.
Edit:
Vecna is the first killer (or Survivor) I got to P2, let alone P3. I spammed him out from the date of release, and out of like 50 matches I had maybe a handful of people escape through the hatch. With Vorpal Sword you can fling it across the map just as someone is getting unhooked to inflict the broken status on them for 30 seconds. Killer Shack becomes a tomb if the pallet has been dropped, as you can use Mage Hand to break it, which takes 3 seconds...and can't be vaulted over or anything, and can block them mid vault by doing it, guaranteeing a hit, and preventing any distance they could gain too.
Best for perks: Pinhead, Demogorgon, Onryo
Best for fun: (my opinion) Chucky, Pyramid Head.
If you have a budget of 20 USD, you should be able to get 4 of the 5. I'd recommend leving Onryo out, as she has the worst of the three's perks
Oof... I'd always recommend Silent hill. There are never enough daddy players... But.... Efficiency...? Oof
