I'd go KV-1. Granted I don't play low tiers anymore unless I absolutely have too, and I only played the 1S when it was an OP tier 6. KV-1 is the big bully of tier 5.
Outdated information. KV1S is the king of tier V heavies now, KV1 got knocked out of that position via power creep.
I already have both though, and won't keep two of the same tank. Will probably keep the 1S when I max KV1
I will defend the +2 spread since it used to be a +3 spread! Be happy for that change.
Fallacious thinking. Just because it used to be even worse, it doesn't mean the system can't be bad now.
Still not as bad as War Thunder's BR system, though. That is a freaking mess.
I played the closed beta of WoT, I exactly know how the mm was then.
Also world of warplanes sucks arse, War Thunder has the better air combat.
WoT still holds a much more interesting tank combat though, I must admit. In war thunder your actions have no real importance, you don't feel so awesome after a streak of kills for an example. Also the physics still suck, and totally break the immersion.
