KDE stuff is prone to fixing bugs in both the supporting libraries and software substantially after the versions that end up in stable distros eg n.0 sucks but n.4 ends up substantially improving the prior issues.

I would suggest a self contained version on stable distros or running on a rolling release whichever is practical.left to take advantage of said improvements.

I would also suggest that performance under Windows may be less tested. I personally wouldn't use it there.
