The only reason to go vive pro is for the eye model or for wireless.
Same res between em but vive pro is oled (worse screen door as a result but better blacks).
Stuck at 90hz vs 144hz on the Index.
Audio is gonna be better on Index as well.
FOV is going to be ever so slightly better on Index depending on how close you can move the lenses to your eyeballs.
