Two VERY different pizzas.
Brick & Wood is a creative, upscale, quick cook, small-size pizza in the Buffalina, Zeneli's manner, while Roseland is heartier, breadier, traditional with loyal locals & longtimers, and more than just pizza.
Two different experiences as well. Both very good.
A peek at Yelp photos will help, if my descriptions haven't.
Nauti Dolphin, subsequently mentioned, is a well-liked takeout option located at the train station. The pizza is styled more like Roseland, but Roseland to my taste is far superior, and I'd choose Brick & Wood if in Fairfield.
