Okay, I've tried the T-10 and it's a fun tank to play. Speedy, nice gun handling (for a heavy), strong turret which borders on super stronk when using the full extent of its lousy gun depression. The hull is still kinda shit, but not 1-4 shit, it's enough to troll T8 tanks. In the end I would say the T-10 is better then the 1-4 in most circumstances.
Therefore:
WZ-111 1-4: 12 Skoda T 50: 56 M46 Patton: 30 T-10: 42
