Not sure if he's considered one of the best, but Martin Kearns of Bolt Thrower has a degree of precision that I think is unmatched by most drummers today.
Since I got a kit, I've taken an appreciation for drummers that hit the kit super hard, so I'm updating my list to include:
Bostaph
Vinnie Paul (haters gon' hate)
Martin Kearns
Kevin Talley
