You could ass well putted Vyper/Vytec in the arena.
But i choose Uwatec, i like the large display. The only minus is that the price, they are a bit to overpriced.
I believe that both brands deliver great computers (despite the flaw on the Uwatec). Finnaly, it's a matter of taste.
But what i also like al lot, is the accent rate read-out on the Uwatec and that you can accent faster at greater depts, this is perfect.
And the MB levels, wel, it feels like thatis is nice to use for when you don't to great to dive, but on the otherhand, you learned not to dive if you don't feel great.
I read

that level 1 or 2 matches the SUUNTO RGBM model. I believe that has to do with the 3 minutes level stop what SUUNTO gives to you after you dove deeper then 6m.
Some people don't like the MB levels, because you don't seee no anymore your NLD, DUH!! this is why --you choose-- the MB level, to dive more conservative and follow the Uwatec MB dive profiel.
If you see a level stop, go up a bit and continue.
