Moral dilemma

Aperture or angle of view? Decisions, decisions....

A: EF 20mm f/2.8 USM: 84 x 62 degree angle of view (on 35mm)

B: EF-S 10-22mm f/3.5-4.5 USM: 97 x 74 degree angle of view (on 35mm)

(View angle taken from Canon lens chart.)

So... candidate A has bigger aperture. Candidate B has a wider angle of view (not to mention that it's a zoom, making it more versatile). Ignoring price, which would be better? (Well, if I were really ignoring price, I'd be looking more seriously at this.)

The 20mm. It's a simpler lens structure and will have less lens flare, which is a big deal on the wide angles.
