Ask any UA regular if they would rather a C or F seat on a p.s. redeye, then tell them it is a 3 times longer flight. I think they'll take F.
It all depends on the angle of the slant. For example, the LX flat seat slants at such a steep angle, it is useless as a flat bed simply because you cannot help but slide toward the floor. LH flat seats are much better because you don't slide down. (OK, at least I didn't.)
SQ Spacebeds are great for sleeping, but in the seated position they are quite hard and the footrests don't come up enough, IMO.
