If you like easy pen, Grille 15 line.
Don't pick any of the autoloaders because they are extremely difficult to play properly. E4 is less good e100, CAX is kinda fun with some good tanks, e5 nerfed is stil decent and the t7-X are all good. The entire soviet medium tank line entails having to spam premium rounds due to low AP pen and high HEAT or decent premium rounds. E100 is ok but personally I find the tiger ii boring and the E75 too slow, and PzKfw is basically a less fun E100 imo because it has a 128 instead.
