There's a reason why WMR is so cheap but I guess it's a cheap way to get your feet wet. People generally recommend only the Odyssey+ from WMR lineup and some complain about its controller tracking. Explorer (with controllers) may be worth it for real cheap but it is regarded as a low quality headset.

Immersion gets better the better gear you have: headset comfort, sound quality, screen, field of view, wirelessnes, controller quality, controller tracking, full body tracking. 

Quest is great as it's self contained with PCVR option. I find it very comfortable, screen is good, it's wireless and has top tier controller quality and tracking. If you don't like it you can always sell it near retail price for some time as it will be a desirable headset. Explorer on the other hand is EOL and offers nothing over other headsets and will be considered no value garbage sooner or later.
