A Mountech front derailer will accommodate the widest range of possible gearing, especially different sizes of middle ring.
Newer derailers tend to be designed for specific gearing step increments, such that the cage may rub against the middle ring when the largest ring is engaged.
I've used standard front Cyclone derailers for various triples with 34-52t total range, and the smooth cage plates weren't fussy about the particular gearing increments. It even indexed perfectly with a 7-speed-era SIS front shifter!
