LTS releses are supported longer (5 years on server), but non-LTS
releases receive updates "only" for 18 months. So after 18 months you
won't have security fixes and other bugfixes for 10.10. If you're
planning to keep your server in production for longer than that and
you're using non-LTS, you will have to upgrade to a newer release more
often. Depending on your situation this may or may not be what you want.

If you install non-LTS over and over, you're getting more recent
software (like newer apache, newer php, newer kernel). If you install
LTS, you're "stuck" with older versions of stuff (then again, there are
backports, too). Again, it depends on your needs.

I personally have a 8.04 LTS installed which is a bit older but it still
works great, and I don't plan on reinstalling anytime soon. Had I
installed 7.10 or 8.10 back then, I would've stopped receiving updates a
long time ago. Which, again, could be fine if your server is not on the
Internet for example ;) like an internal server for developers, or
something like that.
