Depends on the variant you want to fly. If it is the A5 then Duk190, MrKillu2, Boo, Kappa and a couple others. If it is the Dora, Pervert is the ubber stick but he doesn't care much for mentoring, I've tried. The A8 seems to be the middle-child in more ways than one. I know Save (in-game name) flys it frequently.
My take on the 190s, being a proud member of the Butcher Bird Mafia:
The A5 is the purest fighter of them all. Great in boom and zoom and if you find yourself in the weeds on the deck it is the most maneuverable of all 190s. It is the lightest of the 190s, great engine for acceleration, more than fast enough at all altitudes if you fly it smart. Brilliant in a dive. Above 250knts turns with anyone and surprises most, which helps with tallying up kills. And pretty good in a stall fight when needed.
The Dora is the fastest, great acceleration, slowest roll rate of the three though still faster than any other bird out there. Great fuel range as well, pretty good up high though mostly in the 15k range. Due to its longer nose I find it to have less stability as a gun platform, which translates into less accurate shots.
I sense that people fly the A8 because it can carry the 30mm and that makes it seem ubber. At some altitudes it is slower than the earlier designed and built A5, doesn't turn as well, heavier, etc. The real question for the A8 is one, do you want to use the 30mm or not. If so, fly it. If not fly the A5.
The Ta-152 is a different discussion altogether. The F8 is the ground attack version of the 190.
All in all, I vote Fw-190A5 as the best of the bunch, overall.
PS If you set it up right and get your accuracy worked out you should fly with the 2x20mm package of the A5. The 4x20mm sounds fun, though it takes away from your ability to maneuver, with limited addition in hitting power.
