It’s more so that Pantsir as a whole is better (notice how I never compared the VT-1 and 95Ya6 there?). The missile has a longer burn time, meaning it keeps generating kinetic energy for longer, which translates into manouverability upkeep.
If both missiles had the same deltaV and burn time, VT-1 would be superior - however we’re looking at two different methodologies clashing;
- longer sustained rocket burn time but lower manouverability off the bat
- higher manouverability right off the bat but shorter burn time
If we compare just the missiles alone, they could be considered equeal, BUT, Pantsir has a significantly better radar, and said radar sees further both horizontally and vertically, not to mention it has automatic guidance modes (which although not necessary, are a huge help).
Aside from that it has 3rd generation thermals, and… GUNS! Yes, the guns really make it special. It doesn’t need to waste missiles on low and close flying helicopters.
