I've generally been a dry food person, and only recently delved into the fresh food section, with Cucumber etc, for the Bristlenose.
Favorites for many years have been the Tetra Bits, for the Cichlids, Tetras, and Live-bearers, and OSI Shrimp pellets for the Cory's. We have a local brand, 'Aqua-Life' vegetable pellets, that the Cory's also love.
For 4 or 5 years I've been buying 'Sera' foods. I raise my fry on their micron, and micro-gran. Sera Viformo tabs are also very good, albeit expensive.
Recently I'm getting back into the Hikari, with Wafers for the Bristlenose, and Floating Pellets for the Cichlids. Also Tetra have produced a recent slow sinking "crisp", which is a very good all-rounder.
