Shimano’s side swing front derailleurs shift marginally better then the first Gen XTR 9-Speed fronts and reasonably better than the previous non-side-swing front derailleurs if they are set up properly but calling the shifting “instant” compared to HammerSchmidt is like telling Usain Bolt that Simon Whitfield is a fast runner. Never mind that ‘Schmidt could be shifted under load and when not pedaling.  All the other issues (weight, aduction drag) aside nothing shifts like HammerSchmidt to this day - front or rear derailleur or gearbox, including Di2.
