The Gekko is similar to the Vyper, but it doesn't have a backlight and it doesn't have a plan mode and doesn't do gauge mode. There is a way to make the Gekko download your dive profiles, though I think Windows users have to trick it into telling the software its a Vyper by making a small change to the firmware.
The Gekko, Vyper and Vytec compuers all are the same size, which is really nice if you use the DSS bungee mounts instead of the factor straps or console mounts. I don't think the Suuntos are the same size as the Oceanic/Aeris "pucks".
Don't underestimate the value of having a Nitrox computer, it'll be one less thing to change later if you go on a dive vacation that has you doing 4 or 5 dives per day.
Lastly, if you ever decide you don't want the thing, the Suunto computers are among the most popular.
