Rift S at this point is probably the best in terms of cost vs performance.
You'd need to add on a fair amount if you ever look into adding on Full Body Tracking (being able to track your hips and legs) since that uses the tracking systems of Vive and Index, and also merging those system brings their own set of headaches. But otherwise you'll get a solid headset all around.

Index edges out in terms of total quality, but at a higher cost to you.
