I am a big fan of Manjaro as a distro, but I would not recommend it to someone coming from Windows simply because things move fast and break - I've personally had proprietary software that worked at first, but later broke because libc had moved on. My solution (after trying plenty of workarounds) was to run it in an Ubuntu docker, but that upgrade cost me a lot of time and I don't expect somebody coming from Windows to put up with that much pain.

I also don't want to recommend Ubuntu (if I had to pick a single reason it would be snap), but from a problem-googleability-index point of view, it's hard to beat. Perhaps Mint, because it's mostly Ubuntu, but without snap (last I checked).
