Swaybacked horses are famously EXTREMELY comfortable to ride, and having ridden a couple I can a confirm that. American Saddlebreds, which are ridden with very high head carriage (and hollow backs) are very prone to sway backs, I have ridden a few elderly ex show horses that seemed as happy as could be. Still wouldn't buy one.
There are also some lines of Morgan horses that have sway backs. I knew of one that had a long and useful working life, although when you first saw her you would think "how?"
