With the lofts of newer SGI irons being much stronger (as low as 20° for a 5-iron), I am wondering whether these are indeed easier to play than utility irons with the same lofts.

E.g. would a Titleist T400 #5 be easier or harder to play / more forgiving than U510 #3 with the same loft? Or a Taylormade Sim Max OS #4 or #5 compared to a Sim UDI #2 or #3 with the same loft?
