Index is the best complete package an the best for full body, parts break or need replacing but rma will take care of it eventually, has the disadvantage of low stock and high cost and isn't the absolute best in every category anymore.

G2 isn't out yet, but has probably the best image quality, probably not the best controllers and something between acceptable and decent tracking, a little cheaper than the index.

The quest 2 might as well replace the rift and has a surprisingly good display, marred by the fact that it doesn't connect to pc quite the same way as the others and will have some compression or latency depending on the way you connect to your pc, obviously you can use it standalone. Has an obvious problem of battery life and being connected to facebook, but very good quality for how much you pay for, hits above it's weight class.

The rest probably aren't good enough to compete with any of these, but there are other options if you for example want something cheap and just absolutely hate facebook.
