If you want the overall best consumer hardware right now, get the Rift S. It has all you need for $400, no external basestations or sensors required. The quest is an option too if you don't have a gaming PC or like the idea of wireless. Opinions are mixed whether Quest + the link cable are better than the rift S entirely. I don't have either so I can't say.

If you want to spend less but still have a "real" VR experience, the two options to consider are the samsung Odyssey+, or the refurbished Rift CV1 which oculus is selling right now for $300.

If you want to spend more (and don't mind waiting for it to actually be in stock), get the Index for $1000. It is better in most ways than the other headsets but it's not $600 better, so even though I have it, it's hard to recommend overall. 

Re: tracking, the index flat out won't work without the basestations. The headset only or headset+controllers only bundles are only for people upgraading piecemeal from a vive.
