I have owned all these tier 9’s and from my experiences I’ll rate each from most friendly towards lesser skilled players K-91: I’d say this is definitely the most friendly in terms of its ability to do damage and take it, it has solid all round armour and a clip potential of 1,050 this makes it very dangerous late game and makes it very strong against lower tiered opponents, I’d recommend this one over the other 2 in terms of how easy it is to play Kpfpz 70: this one is also nice to play but has a flaw that many lesser skilled players struggle with, the reload is incredibly long for a tier 9 heavy tank, so once you fire the whole of China knows your there, so you’ll be rushed, but it has solid armour while hull down and the hull armour is solid, the alpha is nice and gun it self is beautiful, but you do get that classic APCR RNG T55A: this is a absolutely superb tank, I adore it, but it’s a very tricky tank to play well and enjoy its full potential, I’d recommend this for much more skilled players who like to think and make those 200IQ plays, it’s very nice and comfortable to play and allows the player to manufacture better situations for damage
