I actually don't have a preferred brand... I'm kinda all over the place! I've bought my gear based on fit and features, and on recommendations from fellow divers. I have an AquaLung BCD and boots, a Henderson 5mm wetsuit, an Oceanic computer, and ScubaPro fins and mask/snorkel, and while I haven't yet bought a reg, I'm strongly leaning towards Atomic Aquatics.
