It does seem like linux is having its moment right now. there's the money and effort valve is putting into KDE making the steamdeck and steammachine polished for their hardware which helps all users of KDE. cachyos is making having a rolling distro really smooth and snappy on old hardware and making games work mostly ootb. stuff like winboat and wine will let you use the few windows apps you need. you are kinda stuck though if you want to use something like fusion360 or solidworks. freecad has improved quite a bit but it's still like gimp where it's slightly worse UX in a lot of ways.
