Thoughts on Kubuntu 16.04? Is it stable?

I would like to know from users that are actually using Kubuntu 16.04 on a daily basis, how stable the system is, and if there are any bugs. I tried Kubuntu 15.10 and I had a lot of issues with it.

And please, refrain from suggesting other distros, I'm interested in Kubuntu.

Edit:

Well, I installed Kubuntu 16.04 on my external hard drive, and I'm glad that I didn't installed it directly in my computer. The driver manager doesn't recognize my Nvidia GPU, and Discover crashes when I try to update the system. I will stick with Ubuntu 16.04 for now, thanks for the replies.
