I have done a fair amount of research on this topic in the last few years, although the last time I actually purchased any seed was about ten years ago.
Tall fescue has an edge over other grasses because of the relationship with endophytes (I think it is a kind of fungus that grows on, or in, the grass). Tall fescues that are "endophyte enhanced" can be healthier with less care. The trouble with the endophytes is that it can make cattle, goats, horses and some other livestock sick if they eat lots of it. So varieties of tall fescue have been introduced that are endophyte free or have a variety of endophyte that these animals can digest better.
But if you don't have farm animals, the "endophyte enhanced" will probably be your best bet.
