Please, don’t take it the wrong way, take it in the constructive spirit it is intended as.
The fact that you think these two guns are the same is very telling of the fact that you need to rethink your position on this discussion.
The KwK43 is one of the most exceptional guns you’ll find in this game, at any BR. If you’re not penning anything with it, it simply means you don’t know where to shoot your opponents. 6.7 is not the sort of BR where there’s a lot of margin for error, you simply have to know where to shoot what. Firing centre mass is not something you can rely on.
I honestly really can’t fathom why people think the Tiger II suffers. Last year’s round of decompression has done wonders for 6.7 heavies for all nations.
What you have with the Tiger II is an incredibly powerful gun with a 7.4s reload (which is an outstanding level of firepower for a heavy) and fast turret rotation. It means you can move aggressively along a flank to play anti-flanker, or get to a meta position and defend it tooth and nail, because your reload and turret rotation make you incredibly reactive. You’re lethal at basically every conceivable combat range. You can snipe and you can brawl. You have a working reverse gear. You can sidescrape. You can take out someone’s barrel, and follow up…
It’s a nuke machine. One of my nukes with it has come at 7.7 on Normandy… most heavies in the game are traditionally useless in a full uptier, but not this one, because the gun still works. You just become a very slow medium tank.
Seriously. I used to think poorly of the Tiger II too, but a combination of learning to play it, and the BR decompression around it, has opened my eyes to just how damn good it is. Maybe even 7.0 good.
The two tanks Gaijin brings up as being marginal and probably worth it of a 0.3 BR increase are the Tiger II and the T29, there’s a reason for that.
Now, if you want an example of heavy tanks that actually suffer from their placement, the Jumbo 76, the Tiger II P, the Ferdinand, the very late Soviet heavies are better examples imho. But not the Tiger II, since its gun allows it to effectively multirole in a way that most heavies simply can’t do.
