It's fast (you don't have to build packages from scratch), and it didn't fail me even once, although I heard playing with glibc such way may be dangerous (particularly, downgrading it). I guess it works for other purposes too.
I don't like installing from scratch if there is a way to fix it. I don't like that approach 'unpack stage on top of your system', because it will lead to system pollution: a lot of files might be no longer tracked by package manager after that. But that's just my experience and opinion. I hope it can help you.
