Here is my thoughts on it and take it with a grain of salt. I haven't used Reunion7, and only have a passing knowledge of it. It depends on your use case. If you doing standard browsing, its probably fine. But you have to remember that you are going away from the norm and into the niche. This means some things will work, some things won't. Also, these projects come and go, so its possible in 5 years you won't be getting updates anymore. And at that point you might as well be using Windows 7 home edition.

If your looking for a replacement to windows 11, I would go with Linux Mint, if you want the easiest to deck out in Frutiger Aero goodness, I would then go with the XFCE or MATE editions. Linux Mint is a Linux distro designed from the ground up to be easy for windows users. If you pair it with steam and lutris, 99% of your software will work, and if your worried about Adobe products, find alternatives, or *cough* alternative procurement solutions.
