Depends on the environment.

I manage a large AWS environment at my current gig, and all of our code is in git. With configs in puppet, code in git, I can deploy to new OS version instances in the background, do testing/QA, and then swap out the old OS environment for the new one all transparently to the user.

Now if you're talking bare metal, yes, it makes sense to go with LTS releases.

It all depends on what your equipment lifecycle is.
