When I started with Linux, the first few years I used SuSE. At that time it was quite normal that a lot of tweaking was needed to get things running. But later on when the landscape modernized, it was noticable that SuSE uses a lot of custom solutions. For instance the /opt directory used to be more in use, likewise a lot of configuration was done via YaST instead of /etc or standard tools that can access /etc. So when bugs appear one needs to wait for SuSE to fix them or work around them. Ubuntu did a much more standard approach, they have (like Debian of course) less customizations in place making users profit from both upstream and 3rd party packages without SuSE focus. Anyways, other distributions don't seem to have a tool like YaST which does all the system configuration and has both proper shell and UI integrations. Also KDE feels more natural on SuSE I guess.
