I'm a big fan of canti brakes. Newer designs on traditional canti geometry have made it such that the difficulty in adjustment and pad alignment, and the horrible squealing are a thing of the past. Many companies have brought back the wide-profile traditional MAFAC canti design (PAUL, Velo-Orange, and Tektro) which is insanely strong. The incorporation of fully adjustable V-brake cartridge pads means that you set the brakes up once, and you're good forever; no more farting around with pad alignments every time you replace them. The drawback is necessitating a very long straddle wire, and the wide profile can cause mounting problems with certain rack/pannier setups. Short chainstays and big feet could mean heel-snag for some riders, too.
Low-profile cantis solve the clearance issues, but they're not as mechanically advantaged as wide-profiles. Still, they're very strong and you have many of the same advantages in adjustment. The BR-550 road canti gets high marks consistently, despite my personal bias against them.
LR Calipers will give you a cleaner look if you're aiming for that Euro-continental design, but the longer arms put things at a mechanical disadvantage when compared to a standard reach caliper. The right pads and good adjustment will still give you plenty of braking power in rainy situations, and you shouldn't have clearance issues with only running a 28mm tire. Depending on your weight and how much you haul around on a routine commute, you might be better off with the cantis.

If you do go with cantis, don't cheap out. Aside from toe-in issues (easily fixed), lower tolerances on the pivot bushings and lower strength of the canti arm lead to the dreaded squeal with cheap cantis. My Tektro CR720s haven't squeaked once, and I have a couple of 15 - 18% grades I descend, with a stop sign and busy cross street at the bottom so I've got to come to a halt.
