I think most posts will be I have the X, and Love it!
Since most folks don't go out and buy several computers, and then dive them enough to make a good judgment on the strengths/weaknesses of each, your responses are going to be based on a bunch of experience from users of one computer. So here is mine:
I have the Aeris Epic (AI wrist), and Love it!
It is a bit complicated but it does to much not to be. I have the Atmos II (wrist, non-AI), and it is a bit easier to use vs. my Epic, but it does a lot less. The only differece between the Atmos II, and Atmos AI is the air integration.
All dive computers I've seen show you what you need UW without doing anything more than looking. Most have the option of displaying additional data with the touch of one button. Most do nothing more than display data while UW, but the Epic is one exception.
AI is nice. With one glance you get everything you need to know about your dive.
The Suunto is a more conservative computer vs. the Aeris. I prefer a less conservative computer, as it is easy to dive more conservitively, but non possible to make your computer LESS conservative.
No computer monitors your body, (well maybe heartrate) so Nitrogen loading is based on a theoretical model.
I like wrist mounts. My transmitter works great, and after 2+ years, I have replaced the battery in the wrist unit (Epic) annually, but never the battery in the transmitter. You can check the transmitter battery from the computer.
I think all three choices will provide you with years of use, however think hard about the console option. I know many that have gone from console to wrist, but never the other direction, and there is a reason. Kinda like a pocket watch, how many folks to you know that use them vs. wrist watches... very few.
