Raspup 8.2 is the first one I installed in Raspberry pi 4 (4GB RAM). It is ok but I am not happy with the performance for web browsing. So, I tried Gentoo and Raspberry Pi OS. I got the Raspberry pi 4 as a desktop replacement for the old laptop for my parents. They only use browser or goto youtube.
Definitely, Raspberry Pi OS is slightly faster than Gentoo. Raspup 8.2 performance is the worst among the three. Since they use it for browsing, I have not spent time to do research on how to make it faster. So, I only use default settings.
You can find the OS links below.
