I have and dove(dived) Sherwood (which i'm pretty sure are about the same as Genesis) Dacor, Tusa, Cressi, US Divers, ScubaPro, Oceanic and Atomic. I rarely dive with anything else but my Atomics. I use them for Cave diving, Reef diving, Wreck diving and Deep diving. I have an M1, several B's and a couple of T's. I recently went diving on a liveaboard with dive shop owners and instructors from all over the US (16 of us). Out of 16 divers I think 6-8 had Atomics and then it was split up across the board. On this particular boat Atomic was the clear winner with second place far behind. JMNSHO-M
