I've had both Leer and ARE and would consider them pretty much equal. I'd go whichever I could get better pricing on. As others have mentioned, I highly recommend the vented windoors and sliding or folding back glass.
I have a F150 w/ the 5.5 bed and I'm 6'-0" tall. It's actually very comfortable to sleep in and I can fully stretch out, I just run my sleeping pad diagonally.
