I would personally recommend the base distros and I am a big fan of Fedora myself. Has been rock solid for the last 4 years or so. Although you'll have to choose a desktop environment as well. I use gnome, which imo just looks and feels really good, although it's not as easy to customise. You can also pick KDE, which looks more like windows by default but you have so many settings it's a bit too much imo.
You can always change the desktop later if you really want to, so pick whatever you think you'll like best
