Favourite guns?

I've currently just unlocked the tortoise and while I know I've got great things to come with the 120 the 20pdr on this is probably the most fun I've had on this game. My crew isn't yet but with bond rammer on it I've got my reload down to a sweet sweet 3.5 seconds and let me tell you this thing can shoot so fast it negates repair kits

Straight after repairs I've already damaged their tracks again and 3 seconds isn't long for most tanks to get back into cover. Pew pew pew goes the tortoise iust come off a game facing off 4 tier X tanks and they sucked at hitting me but I will literally able to keep them from advancing just blowing tracks out one by one. Came away with 8k bounced a mediocre 1k damage and 2.5k assisted. I know that isn't groundbreaking but God damn it was fun.

So yeah what's peoples top guns at the moment, I hope it hasn't spoiled me for the reload on the 120

Happy tanking
