I only know of Rebulx who has tried the old tweetage in the v4. I haven't heard it myself so I can't say.
My v2 tweeters broke up at higher SPLs. The v4 do not. What I didn't know until I got my v4 was how much narrower the soundstage was with v2. V4 took care of that with improved dispersion of the tweeter and likely improved hand-off between the mid and tweeter.
The v2 highs sound what many would describe as "clearer". To me they sound more clinical, not as natural and not as nice to listen to for long.
Not sure really who is brain damaged. Me or you and Rebulx.
