Are there any match-ups where Rose's U1 is better than U2?
As far as I can tell, U2 is like a free win if your opponent is low on health, and you can still definitely use it as anti-air, watching for their position during the pause and doing the appropriate air grab after the orb hits. A lot less damage, of course, but U1 is only good for anti-air, where U2 has a plethora of uses, defensively and offensively.
