Cons
Con Some clear differences from other Linux distros
This might be a systemd issue or OpenSUSE specific, but changing certain text files does not update things. They must be edited in YaST, or in /etc/sysconfig/
Con Old kernel by the Leap version
Kernel in Leap 42.3 is in version 4.4, that's pretty old.
Con Poor support for nVidia drivers in Tumbleweed
No native driver support and nouveau may be broken, especially for KDE, and not suitable for some GPUs.
Con Bloated and slow
Con Short lived distro
Every release lasts 18 months only before needing a major upgrade.
Con Updates
Not a huge problem, but Tumbleweed is better updated via the command line.
Con Massive ISO download
The base ISOs are over 4 gigs, so be prepared for a very long DL if you have slow internet. There's a network installer version, but that just delays the long DL.
Con Bad support to NTFS fotmat.
Con Limited community support
The community is fairly small, and there is no indication on the forums regarding when a issues will be solved.
Con Packman repository has to be added to have good software support
Con Startup takes a long time
Con Updates
Not a huge problem, but Tubleweed is better updated via the command line.
Con Complex permissions policy
