Yes, I think it’s basically the same. With Aeon you get a lot of it automated and already set up, which is good if you want the kind of system that Aeon is. It’s opinionated, so if you want to tinker or want something else I think Tumbleweed is better.
What started as openSUSE Micro Desktop is now openSUSE Aeon. It’s still RC2, and RC3 will probably be easier to do a clean install since it will add full disk encryption, but if you want to check it out now it’s reliable and works well.
