Index is better in almost every way but significantly more expensive. Rift S can be got for $400-ish while an Index will set you back $1000, and the differences are relatively minor (especially if you're new to VR and don't have much to base for comparison anyway) so Rift S is kind of considered the best value for your money, while the Index is if money is no object and you just want the best tech available right now. Quest is also an option if you care about portability or don't have a powerful PC, though it's otherwise inferior to the Rift S in most ways.

Other differences maybe worth noting are that the Index requires external trackers that need to be mounted on your walls (some people don't like having to drill their walls, some don't give a fuck, but something to consider). The Rift S tracking is all based on the headset and controllers and doesn't need any external units, though this does create a few blind spots that the Index wouldn't have (mostly if your hands are way behind your back or something) Also I've seen some people complain that the Index controller has some build quality issues where the Rift ones are much more durable/reliable, and Indexes are also temporarily sold out until like February. On the feature side of things Index supports full finger tracking out of the box while Rift S does not (though there's talk of adding something similar through software later, we'll see if it happens) as well as higher refresh rates, resolution, and FoV
