The A321 holds 13 AAA ULDs. The 757-200SF we've got holds 14 AAA + 1 LD3. For the bellies, our docs show a volume of 53cbm (cubic meters), Airbus says the A321 has 52cbm. Therefore, the 757 has roughly 20cbm more volume. Total volume of a 757 is around 230cbm vs around 205 for the A321; a rough 10% difference. I've no data on payload capability for the A321, but would guesstimate at around 23-25 tons vs 28 for a (Boeing) conversion. Please note, it's of course possible to increase MTOW on the 757. I belive we can go up to 111tons on some of ours without modifications. Then again, we've got the -535C motors and I would expect a -535E4 engined version to be able to go higher still. Will give you more range most of all, as you'll be bulked-out (as an integrator) at around 25-28 tons.
I appreciate there's a 757 conversion on the market that'll give you 15 AAA positions (same as a 757PF), and therefore a further volumetric advantage.
The A321, however, is much leighter than the 757. We're talking an operating empty weight of 48 vs 60 tons! Sure, the 757 has superior performance over the A321, but carrying around those big fans with a 40k lbs capability is expensive if you don't need it. The A321 gets by with around 27k lbs.
So, if your requirement is to carry around 25 tons for no longer than around 3 hours, the A321 seems to be the better option. For longer sectors, or for sectors where performance is an issue, the 757 would be better.
I've personallly got nothing against Airbus, I'm sure they make fine aeroplanes. However, the deciding factor is not whether I personally like it or not - it's about economics.

Airbus has never been much into the freighter market, and there havent't that many A321s on the second-hand market with a low enough price to justify a conversion program. They are starting to become available now, which is why Airbus has geared up and are starting to actively promote them. Hopefully they've listened to us last time we spoke and moved the cargo door from position 1 to 2!
