I’ve been using an Aeris Atmos II for a few years... Never had a problem with it, works great...
However, if I were to upgrade (and I’m thinking of it), I’d be moving directly to the Galileo Sol (Uwatec). Awesome wrist computer.
Your considerations are: 1- budget; 2- gas (air? air/nitrox? trimix?); 3- do you prefer a liberal or conservative algorithm? Suunto usually uses a very conservative algorithm, and Aeris more liberal, so you’ll be into a deco obligation with the Suunto long before Aeris. It’s a personal preference.
