From what I understand, there are a lot of FAs (especially senior FAs) who like the short layovers, because it allows them to get all of their hours out of the way without being away from home as long. On the other hand, I've also heard there are a lot of FAs who don't like them because of the reasons already mentioned (fatigue, etc). I guess it boils down to if you like it, bid for it, if you don't, avoid it. I've worked with the pilot group, and I know they have some similar issues where one group of pilots likes one thing and another group likes another. For instance, commuters love 4-day trips, because they only have to make their commute once to get in a lot of flying, while non-commuters would rather fly a lot of 1-day turnarounds and spend less time away from their families. To each his own, I guess.
