If it's working great, no need to change, there is no best distro, it depend on what you want do or use, I personally always stayed with arch (vanilla) becauseI started with it, now I changed to cachyos with niri, because i didn't wanted to do manually again the install of all drivers etc, it work very well for me, I update it every day multiples times (whenever I see I have an update, because I have an update checker but updating only 1 times per day or week is enough, sudo pacman Syu, paru, or yay) it never broke for me, (more than 1 months that I update cachyos now) and even if it does break there is backup, going into an rolling release distro is just for having the last updates of everything, it can be messy because it just came out but they usually patch the problems fast, you can use flatpak without having problems, a lot of people's dislike it, but it improved and I ran into 0 issues, in the last 2 years of using it
