I don't think an ordinary recreational diver should buy a better computer than a Zoop (or an Uwatec Aladin Prime). OK for dives on air, OK for nitrox, conservative with a proven RGBM algorhythm... If somebody wants to be a technical diver he has to change too much items in the equipment, the computer is only one of them- and the Suunto has a good reputation so it can be sold easily later or keep as a secondary instrument.
Anyway the color of the Zoop makes it different from the Vyper and the Gekko, that should be the main reason.
