Yeah, those are the same reasons I chose tumbleweed. Plus the rolling release.
I hope you made your system partition large enough. I had about 20G for / (excluding /home), which used to be enough for kubuntu, but quickly ran out of space on tumbleweed. I assume because of the Btrfs snapshots.
I reinstalled tumbleweed on a larger partition. Then couldn’t install the proprietary codecs, because of an error I couldn’t resolve.
Installed it a third time recently, now it runs smoothly.
