This is just going to be the Ness discussion all over again. A bunch of people telling you that you are wrong, but you ultimately ignoring it LIKE YOU ALWAYS DO, and eventually people get tired of trying to convince you otherwise.
Bowser is clearly a lot better than he was. You made the original statement that said Bowser is worse than he was in vBrawl. It was clearly false. I don't feel the need to argue with you on that at all.
If you are simply saying, like JOE said, that you think Bowser's relative placement is lower than where he was, I can agree with that, and that would make this a miss-communication on your part. That's fine if it was a communication error between us, but I can't agree that Bowser is lower than where he was placed in vBrawl if it wasnt.
I would just like to leave it at this statement: While Bowser still has similar weaknesses (but obviously much less drastic, as his weakness to CGing really isn't even there, as is Sheiks Ftilt nerf), they buffed his strengths enough to make up for it. I think the root of the issue is that you underestimate how useful having +1 to a single move is. Adding +1 to a LOT of moves, especially GOOD moves like upB Ftilt and Fair, really makes him stand out for hitting hard, despite not being able to hit as often as someone like G&W. +1 to G&W's Fair would be really significant move buff, so just think how useful a series of those buffs are for Bowser.
I never thought personally that a bad recovery is an issue at all for Bowser. His recovery isnt a "candidate for the worst" like you say, for one thing, but recovery can be remedied by having great DI, and DIing hits to the upper corners of the blastzone. Saying his is the worst in terms of predictability and being unsafe is plain false when you consider everyone and their mothers know how an Olimar or Link are going to recover and their lake of invincibility that Bowser can at least boast. Bowser doesn't have huge issues for defensive gameplay, like you suggest he does, whereas Ganon does. He has numerous options for punishing spotdodges, dair is so much better equipped at beating out air dodges, Klaw is one of the best anti shield moves in the game, Bowser has the ability to BREAK shields with DownB, firebreath is safe on shield and if they spotdodge it, etc etc. I don't think this is ultimately among his fundamental issues.
I'm not going to argue beyond this point about Bowser, though. You are like Yuna for the fact that you don't stop arguing and you have your mind set, but Yuna could boast the ability to be right a lot more than you can. Feel free to contest my points, just don't expect me to keep arguing with you.
Also, I secretly hold out hope that you meant Bowser is worse relatively compared to characters instead of being worse than his vBrawl counterpart. That is something I can agree with, but I don't agree with him being worse than he was at all.
edit: Just because I don't know if you still check the G&WBR or not, I wanted to post here that I confirmed your bit regarding G&W's head not having a hurtbox on his Usmash! I always suspected something like that, but your thread had me check it out thoroughly. Thanks for that!
