It's very stable and it has all of my favorite software preinstalled (including firefox). I really like that there are so many different flavors to choose from with this distro. The only thing I don't really like is that you cannot upgrade an existing install without going through multiple versions. If you want stability then go with mageia but if you need something new or have specific needs in mind, try out other distributions such as ubuntu studio. I'm using it primarily because i use linux every day at work and i needed a reliable distribution which supported everything i do.
