It's hard to speculate when we know nothing about it...

We don't even know if it's manned by 2 or 3 men... We don't know the tech system inside... We don't know anything about the reactive armor and reactive protection... We don't know.. Well, the list goes on.

My GUESS is that it's a very competent tank, Russia isn't exactly stupid, and if they choose this version to mass produce they probably have good reasons.

Does it beat the western tanks? I have no idea... But I wouldn't be surprised if it did, as it's a new model whereas we in the west have just upgraded old models for quite some time now...

Summary: I wouldn't want to meet that tank in a dark alley...
