there's nothing really great about the SW series compared to Airport series. it's which you think suits your needs better in fact i took some time at tk deciding between the SWHD and Antidote v2.0. see my post below for their similarities and differences.

you can't compare it with the UD series cos those are shoulder bags. shoulder bags and backpacks both have their uses. i have SWHD, UD60 and UD30. which i use depends on my the gear i'm carrying at that time.
yep, every individual has different needs and preferences, hence, it all depends on what works for that person. there is no one size fits all bag.
