Without a doubt going to 2k20 on day 1, i mean theres a ton of cool new moves, for me my favorite being 2 Kamigoye's!!! been waiting for that move for ages to be put in. Plus the new people in it like The Fiend, Ciampa, Murphy, Riddle, Keith Lee, and all the improved models like Ronda, McIntyre, Rollins, Lashley etc.
I know theres been a ton of shit thrown at the game by people but i have faith they'll be a patch to sort some things out, like the entrance lighting i'm sure that'll get patched, hit detection etc, plus i've heard some say patches will likely be much easier to put out now with yukes not with them anymore.
Also Denk or Pulse i think said if you like 2K19 you'll probably like 2K20, so no point in not going to 2K20 really.
