Linux

Disclamer: last time I used OpenSUSE was very long time ago. Probably somewhere in 2018.

When I switched back to Gentoo, Gentoo had more packages in base repo, was more configurable and easier to fix and felt more convenient to me(especially for development). Also easier on resources in casual use. It was important to me since at the time my system had very small amount of RAM, while I wanted to host minecraft server with many mods and play on it with friends. Installing cross-compilers is very easy with crossdev. And I think there were problems with having multiple versions of gcc installed. The only downside I can think of is slower update process(especially compiling firefox/chromium/libreoffice/rust), but in return you get the system, which if breaks, you know how to fix it.

Would I recommend Gentoo to everyone who wants to install Linux on their own regular x86 computers and be what people call a regular user and doesn't want to understand how system works? Rather no.

Would I recommend Gentoo for someone who wants to install Linux for their granny and already knows Linux or even has Gentoo? Rather yes, stereotypical granny doesn't care about distro, she only needs browser and working sound.

Would I recommend Gentoo for any kind of developers(except webdevs, they are separate species)? Absolutely.

For gamers? It is one of reasons I choose Gentoo.

For tinkerers? You know the answer.

For wierd ARM/MIPS/RISC-V/ELBRUS computer? Very yes.
