One advantage to using the square food-service buckets as panniers is that you can also use them as stools to sit on when they're off the bike, try that with your fancy Ortliebs! They are kind of bulky though, I have generally preferred to stick with the coated fabric commercial panniers (Arkel these days, though I have a couple pairs of beat-up Ortliebs which I have patched up with Sugru).

My anatomy evidently favors Type-II (fast-twitch) muscle fibers for cycling, so large cross-sections kill me in general. I can't spin through the kilometers in low gears like some can. So aerodynamics is more of a concern for me (and others with similar anatomy). The jugs in TFA are lower profile than kitty litter buckets or other square things. However, tailwinds could make up for the drag on good days!
