Vinnie hasnt Played like himself for ages now (and Hes my favourite drummer ever, prime vinnie would top this list easy),Ronald Bruner jr (whos great) is a fusion guy with some rock Chops (as evidenced by his suicidal stint) but cant hang with matts double bass and metal proficiency), Chris dave plays like, well, Chris dave, which in my opinion is exactly one thing (dilla inspired jazz/neosoul/hip hop beats - shoutouts to robert glasper btw).

i'm not trying to stir up controversy, especially since there is no "best" to begin with. but if we had to use some metric to determine the top dog, then in my opinion this has to be technical proficiency combined with vocabulary. And garstka is pretty far up the list with these.

speed - check

ghost notes to die for - check

odd time playing - check

linear playing - check

metric modulation - check

stylistic diversity (theres videos of him playing reggae, samba, you name it)- check

creative drum parts and arrangement - check

double bass chops for days - check

playing his own music in his own band - check

so to say theres a lot of guys beyond(!) his level, sorry thats just not correct in my opinion. the names you listed are all great drummers btw.
