I've been meaning to do the same thing for a while now. Which distro are you thinking about? I had been leaning towards Ubuntu...
Re Win 10. Guess I'm in the minority, but it seems to be working better than the Win 8 that came with my laptop (which I bought 5 years ago when I was FIRE'd). I don't use Edge, just Chrome and have been moving more and more to the Google world with less and less Windows traditional applications in my life. The Google system was the best compromise with my mobile transition (Android phone and tablet).
The distro I'm thinking about is Linux Lite. It's a distro that are geared towards those switching over from the Win world. A new release just came out. I have the previous version (3.8) on a laptop and that reminds me of Win 7.
Another distro I looked at briefly is Peppermint which I like too (the software manager uses the same one as Linux Mint), but found lite more intuitive.
It's fun to go to distro watch and see what flavors are out there as seems like a new one pops up each day.

I went over to the dark side (Apple/Mac) about five years ago and never looked back and have no regrets whatsoever.
