Other Gorilla & Ohm Class packs?

I'm trying to compile a list of packs for my bf to look at and choose from. But off the top of my head, the only two packs coming to mind are the ULA Ohm and the GG Gorilla (probably because these are the two I've been eyeballing for myself for months). I was hoping to be a little more fair-handed in the roundup though…

Are there other packs in the same class as these two packs that I should be including in the roundup?

Other packs in this "class" might look like:

Comfortably carry ~25lbs
~Volume: 3000 cu in (50L)
~Weight: < 24 oz
Internal Frame
Hipbelt
Hydration sleeve (or an option for one)
