I have played all three factions to rank 12 and when I first started playing, I thought the Tanks on the Russian side where the best by far. Then I played with American ones, and I have to admit the American ones are way better.
Now I am ranking up my UK tanks (i started on UK but never played with tanks much) and I have to say that the UK tanks even out class the Russian tanks.
Both have much longer rangers for their specials, and both are faster by far. In head to head matches I have had no real issues (although I have yet to meet a vet russian tank with my UK tanks).
What do you folks think? I'm really thinking that bumble bee is junk now over all. The range on it is too short.
