I think that it is impressive, but not necessarily that useful? In particular, you can’t really trust what they’re saying to be accurate so it doesn’t actually give you that much usable information.
Very cool, but I’m not sure what I would actually use it for.
As long as you have your windows license key you can change your mind later so really you can do whatever. I’d recommend giving 100% linux a try if that seems fun. Obviously you’re gonna want to back up any interesting files that you have on windows either way.
