In terms of specs those packs are all very similar. My choice would either be the Mariposa or the Exos.
The Mariposa is the lightest pack and from everything I have heard they are well reviewed. However, it is also probably the most expensive and can't be tested in store here. I have owned both the Exos 58 and 48 and love them both and would definitely recommend them. They are also about the same price to buy at full price in Aus as the Granite Gear Blaze 60 is on Massdrop. The Blaze 60 is supposed to be a decent pack, but it is heavier than the Exos and almost the same price but can't be tried on in store in Aus. Lastly, I have only heard good things about ULA, but the Catalyst seems like overkill. It is a 75L pack, but can only hold about as much weight as any of the others before it gets uncomfortable. Assuming your gear is quite light and not too bulky already (which it should be if you are moving to a pack like this) then you could probably go for a different pack in the ULA range like the OHM 2.0 or the Circuit (which is still probably overkill on size being 68L).
The one disadvantage to all of these packs is the mesh pockets. I find they easily tear on vegetation, but can be fixed quite easily with a bit of tenacious tape.
