Yes, I certainly do.
To the best of my knowledge, a *buntu is a *buntu is a *buntu. In other words, ANY *buntu is going to have the same driver support.
But your question makes me think you're having (or have had) problems with some item/device/component. Since that hasn't happened to me in years (the last time was circa 2007 when getting Broadcom 43xx wireless cards working took a little tweaking), I'm wondering what your specific issues are/were.
As for WHY I prefer Kubuntu, let's start with its
infinite customization options--and we're talking via its settings; we don't even need to go into doing stuff at a command line. As I've said before, you could literally work full-time tweaking your settings, and never be DONE. I love the beautiful, polished, look of KDE. I also, in general, prefer KDE apps over their GNOME counterparts. So a fresh install of KDE/Kubuntu lets me hit the ground running because it's already installed basic apps I'm going to use. There are some notable exceptions, such as gParted and Synaptic, which I install IMMEDIATELY after I'm up and running. But keep in mind, as I've mentioned before, that you're perfectly free to install/use G apps on K, or K apps on G. They'll run just fine.
