I ran LMDE for a long time, so I would never quibble with the argument that rolling releases are less stable than point releases, it just depends on your luck, your strategy for using linux, your definition of stability, and your ability to fix things, and that varies enormously between individuals. But if you follow my rule above it doesn't matter how unlucky or unskilled you are, you NEVER experience breakages for longer than about 3 minutes - which is how long it takes to reload a disk image with qt4-fsarchiver.
I just don't know why people don't get this, the tools are there, they are free, and in the case of qt4, pretty easy to use (less so for clonezilla). If people choose not to take advantage of them then they either don't understand Linux or they are using debian stable and believe me I have done that as well and you don't want to be doing that.
The other simple strategy for using Linux is dual booting - and I don't mean with windows. If one distro breaks you use the other in the meantime or you use the other to fix the broken one.
Personally I recommend both strategies in parallel.
