Nah, Rosé gives only a small SA boost to allies, this one gives a big passive boost (meaning that it's much more effective) to all Extreme allies. Combined with the increased stats, increased SA multiplier and the extra chance to crit, this one would definitely hit harder.

I would only separate the buff for allies from his own in terms of wording, otherwise it can be a little confusing.
