Update 1:
Stable as in, less likely to crash or cause any issues when future updates or security fixes are applied.
Original question:
I was about to post this question in askubuntu.com, but wanted to avoid bias views infavour of ubuntu, as I am sure most people like ubuntu over at askubuntu.com.
My question is, if I wanted to do a minimal base command line installation of ubuntu 12.04 or debian testing (currently wheezy), which of these 2 is likely to be more stable over the next 5 years? 5 years because Ubuntu 12.04 will be supported for 5 years, and Debian testing is a rolling release afaik.
I think ubuntu 12.04 will be more stable for various reasons even though it's based on debian testing, but just wanted to find out from more knowledgeable people, if ubuntu 12.04 really will be more stable compared to debian testing?
So basically, I want to start off with a minimal command line install of ubuntu 12.04 or debian testing and add a minimal xfce to it using -without-recommends, and would like to know which of the 2 will be more stable as a desktop os, not as a server os.
