Now 100% more demonic
Having a strong Aqua Jet also makes it a good revenge killer to Volcarona, though you can't switch in safely with almost all Volcarona running Psychic for Toxapex.yh it really got a lot better post mage and cinderace bans. Even more importantly than slowbro itself losing usage IMO is that it doesnt run helmet nearly as much now, and helmet in general isn't that popular anymore, which is great for watershifu, as it no longer has to fear getting massively punished for clicking the move it wants to click most often. It can still get walled, but it doesn't get punished nearly as hard for just clicking moves as it did before.
Also there has been a slight rise in physical defense setup mons like iron defense skarmory, iron defense magnezone and bulk up corviknight which tend to use substitute(except skarm), and surging strikes is great to put the pressure on such threats; while not a counter as such sets tend to run super effective moves, it can serve as an emergency check if they are already set up and hard to remove and/or chipped.
It still ain't a world beater like its cousin, but a lot of things that made using it REALLY miserable are gone or not popular
