The thing is tankies love the real Russia as it is. Some in alt-right like the propaganda image that has nothing to do with reality. And some just follow „enemy of the enemy is my friend“ for better or worse. So the nature of the problem is widely different too. The whole BS surrounding Tucker interview is a good example IMO.

Here in Lithuania alt-right is very anti-Russian since we have both pretty good on-the-ground information as well as, let's say, historical experience. It's funny watching our alt-right meeting West alt-right.
