Personally, I love tinkering with the latest tech, I love the Port System and I love KDE. I probably also love stability, but that does not fit too well with the other stuff~ That's why, for me, Gentoo is the coolest desktop distro and StaLi for my RasPi's. Well, I guess for normal use, I prefer KaOS, which I have on my laptop.
I also tried out Suse, Kubuntu and Arch for my desktop, but I liked neither.
