Cons
Con Little / no third-party support
Like it or not, most third parties don't want to deal with less-popular distros. So most of them only support Ubuntu LTS and those versions of RHEL/CentOS that are still supported.
Con Complex multimedia codecs and plugins installation
Con "Online Update" update in YaST control center only works in openSUSE Leap
Con Packman repository has to be added to have good software support
Con Slow and painful unfortunately, especially compared to other modern distros
Con Installer doesn't recognise partition table SOMETIMES
On a couple of occasions the installer has told me one of my disks is missing a partition table but it definitely has one and other distros haven't presented this warning.
Con Default theming not to everyone's tastes
The default icon theme in particular is IMHO pretty ugly. Easily changed but if you like to just plug & play without changing themes it may not suit you.
