Nothing wrong with most of the British tanks I have played to be honest, Crusader and Covenanter are both good to play and apparently the tier 6 is even better and the mediums are pretty good as a whole. Heavy line has fewer advocates.
And if you get frustrated you can just troll people in the KV2
I'm tempted to stump up and buy the KV2 again, a platoon of these would be almost unbeatable.
