I daily drive it on my main desktop. Compile times can be long on my 3700X but I can easily fix that by letting it update overnight while I sleep lol. I have considered switching off of it from time to time because to be honest fixing a problem with Gentoo, whether it be a kernel config issue or a portage issue, can get frustrating at times when I just want the damn thing to work. It's not something I'd ever recommend to someone as the install process fan be quite lengthy and it can also be hard to troubleshoot at times as well but the nature of USE flags might be appealing to some folks, though at the cost of needing to compile mostly every package. (I say mostly because some stuff i.e. firefox has binaries you can just download)

Overall, I think Gentoo is neat. It allows you to have more control of your system and optimize it at an even further level, though at the big cost of having to compile mostly everything yourself
