Well, see, I ride my bike to commute...not to carry home a week's worth of groceries. If grocery-getting is part of the requirement, well and good, but I didn't hear that from OP.
(and if it were, I'd go with a milk crate over panniers)
I'm not familiar with trek's mounting system, but if it falls off then it is poorly designed.
Being able to pick up beer and munchies on the way home is a huge advantage. The OP wanted to know the advantages of panniers vs. backpacks, so i simply stated one. If you want to pick it apart with a fine comb then feel free. BTW a milk crate is tiny compared to open ortlieb rollers, and less secure too since with the ortliebs you can cinch down the top.
