I can offer an indirect opinion. I have m60ti, love them a lot. But I also have v4 m2 and m3. V4 is amazing. A tangible upgrade overall. The tweeter is smoother than ti and the soundstage width and depth are better overall. Depending on prices and budget you are working with I’d slowly build up the v4. But if budget doesn’t allow and the convenience of a nearby v2 compliments what you want then that might be too good to pass up.
Sorry that probably doesn’t help too much but it’s what I can offer from my experiences.
Bottom line for me, v4 is really good.
