2k18. I might get FPWW, because it has online multiplayer, but I was never a huge fan on the gameplay for the Fire Pro Wrestling games. The WWE games haven't really done too much for me in terms of single player for a while, but I still love playing them online (when the online is working ... although, there is some hilarity that ensues when it's complete garbage) and I vastly prefer the actual gameplay over FPW's more SNES-style gameplay.
Related note on that working online bit I mentioned: Two days ago, I was playing a three on three tag with Brandon (black, not Canadian) and Rufus, against three computers. For whatever reason, the online in 2K17's been disconnecting us in our matches, but in a weird way. Like, two of us will continue playing the same match, while the third one (usually me) will separate. But, the matches continue, with the third guy being replaced by a computer for the other two, and vice versa. Except, we don't know when this happens. There's nothing to signal it in-game. It just happens. The only way we find out is if one us starts talking about something happening in the match and someone else points out it's not happening for them.
Anyway, in the three on three, Rufus was in the ring, Brandon and I were on the apron. Brandon entered the ring without a tag, so the referee started counting him. At some point here, I was disconnected from them. So, on my end, Brandon's character stayed in the ring for the five count and got DQ'd, but for them, he didn't. Rufus' character was still in the ring for me and the AIs, when replacing people via this weird disconnecting thing, get really stupid. So, Rufus' character wouldn't tag me in. By this point, we all knew that I disconnected from them. But then I started saying I was gonna get a weapon and get myself disqualified. As I said this, and narrated what I was doing, they noticed it happening on their end. So, somehow, I got disconnected from them, but then got put back into their session. But on my end, Brandon was disqualified and in theirs, he wasn't, which completely fucked everything up. When I got in the ring and hit someone with a chair, I was disqualified on my end. But for Brandon and Rufus, because the game was confused as fuck, my character wasn't disqualified for them. So, on my end, it was Rufus vs. three computers and on Rufus/Brandon's end, it was all three of us vs. the computers, despite us, at this point, seeing the same match.
In another match, just a triple threat with us, I was disconnected from them and won the match on my end. When you get disconnected like this and win before the match for the others finishes, you just wait while your characters stand still in the ring. So, I was waiting for them to finish up on their end for about two minutes, when Rufus' character suddenly got up and attacked me. I couldn't do anything. The match was over and I couldn't control my character, so I had to just watch Rufus' character go to town on him until their match ended.
So, to summarize, 2K17's online is hilariously fucked. I hope 2K18 fixes that. Community Creations is also damn near impossible to access. That said, I'm still more excited for 2K18 than FPWW, because I simply enjoy the gameplay more. I also enjoy creating wrestlers more in the WWE games, due to how much more detail I can add to their appearances. 2K18 better add in the sleeve tattooes they took out randomly in 2K17, or at least add new ones, though. There wasn't a single good sleeve tattoo, because they took the good ones out. Buncha fucks.
