To me, it seems as if openSUSE Aeon is heading towards providing an even more stable rolling release distro experience than what people have come to expect from Tumbleweed. However, it seems as if lack of customization/tinkering -even more so than what we expect from other ‘immutable’ distros- will be the tradeoff. Personally, I regard the diversity in vision for these projects as a net positive; let’s see what sticks you know. The project is still relatively young, though.
