Just flew in the 77L with QSuites LAX-DOH followed a few hours later by a non-QSuites flight in a 350 ex-DOH. After trying QSuites several times, now, I can honestly say that I definitely prefer the previous generation J seating (the one currently in the 380). While clearly not as private as the QSuites, they also don't feel as closed in. QSuites have a lot packed into them, and there's really no room to move. I do feel a bit claustrophobic in the QSuites, and I'm not claustrophobic at all. It also feels like there's more miscellaneous storage space for stuff in the earlier J product.
