I am looking for a distro that is based on Gentoo or is heavily inspired by it. I am a long-time Gentoo user and Debian on system where I don’t have the time to maintain it. I love the flexibility of Gentoo, but although my hardware keeps up, I find my self often not willing to wait hours for an update on my main machine. I am glad that there are some binary packages for some programs and I use flatpak, too. But even though, updates take too long, time I want to spend using my computer. I thought of going to Debian everywhere, because it is stable and does not move too fast regarding major updates. So, Arch-based distros are no option for me.
Can someone of the community recommend any Gentoo-based distros?
I second this. It sounds that you want a rolling release distro. Suse Tumbleweed is also a good choice.
You both right about the rolling part, but Arch has one problem for me: There is no dedicated stable version I am aware of.
