Good answers so far. Want an easier one?
First, pick the tech instructor you are going to use and get his/her opinions and maybe even borrow one from the instructor during class--you will probably mostly dive by tables while training anyway.
Next, pick the people you plan to do dives with and determine whether you will be doing mostly air/nitrox or trimix dives, and whether you will be doing light deco a little past recreational depths or doing heavy deco at depths past 200 ft. Then go through the computer decision-making process with your dive buddies.
Note: The Vytec is the least expensive and easiest to use, and is perfect for deco dives not too far past recreational range. And the bonus is that you can use it in gauge mode as a back-up if you later decide you need one of the more expensive units.
Just my opinions.
