I would avoid openSUSE which just wants to be another Red Hat (Aeon is just a shitty Silverblue and the project lead hates KDE) and SuSE in general has been hostile towards free software in the past and will likely do so again if they had to choose.
That’s disappointing to hear. openSuSE is pretty much my go to to recommend new people exactly because from my experience with it it is well maintained but not entangled too much in corporate bullshit. What have they done?
