I'm running M60ti mains with a VP180v3 center and the match is really good.

It's hard to be sure, but based on listening reports from others I get the impression that if anything the v3 is probably a bit closer to your ti's than the v4. I'm sure either would be fine but I would be looking at the v3 if both were available.
