I'd say you have three main options.
1. Valve Index, it has the best VR tracking and has a high refresh rate display.
2. HP reverb g2, it has the best overall display in terms of image quality, was designed by Valve, and is cheaper than the Index.
3. You could use the Index's controllers and light houses with the HP headset. This would require you to do some tweaking to get it to work. It's also the most expensive option. But the youtubers that have done it say that it is the best wired VR gaming experience.
