When I was an Ubuntu user, I did enjoy getting a new OS release every six months. It really matter if big upgrades didn't come every time, but it was something nice to have even if it was just for novelty sake.
Now that I've move to Linux Mint, I've come to appreciate long-term support software. Even tough the big releases come every couple of years, the three point releases that come in-between makes the wait worthwhile. The best thing, is that if any big upgrade in a component of the OS can be come with a point release, not having to wait until the next big release to come.
To be honest, the long-term support model for the OS has won me over. Mainly because it simply has proven to cover all the needs I've for my computing needs without having to worry about my system braking every 6 months. Which, with Ubuntu didn't happen to me.
What's best, Linux Mint's point releases keeps my system reasonably up-to-date without having the worries of upgrading completely every time.
So, if you want a good Linux distro for general computing with support for at least 5 years, but with an option to upgrade to a new version every two years, Linux Mint got you covered.
