Just snagged a Peregrine on a Revo frame but have not had it out yet. Good question.
I have had all 3. I did not care for the hip belt on the Mystery Ranch. I really like the Exo 2000 for a day pack/meat hauler and maybe overnight. The 22 Mag is a good day pack/meat hauler as wells. The Kifaru hip belt is probably the best in the business, especially for hauling heavy loads. Dunno order both and send one back. Hope this helps.
I had a Guide Light with a Pintler. The belt was not substantial enough for me. I've had other Mystery Ranch packs over the years ie Crew Cab, etc. I do not have bony hips however. 5/10 205. I just like the other two belts better. If there is a new frame/belt from Mystery Ranch I have not tried it.
