I was tired of upgrading leap, not that easy when you have a complex
system, and now run Tumbleweed. Since "Evergreen" (remember?) Tumbleweed
become a very robust distro and I fond easier to fix minor glitches from
time to time than have lot of them once every two years.
Exactly the same experience here. At least on my development laptop and a couple servers.
The trickier part in deploying Tumbleweed everywhere is that we do a binary install of our software (a huge package with hundreds of programs). Staying at the same version of the things that are Tumbleweed when the systems are off line and need to be updated at different times would be a logistic nightmare.
So we are looking forward to slowroll. I have not had a chance to test what it currently is. It's on my list.
