I have the Versa Pro and sometimes wonder if I made the right choice. I like that it's not as conservative as the older Suunto but I hear the new Vyper's are RGBM now. Another thing the Vyper's do that I haven't figured out how to make the VP do (and don't think it does) is run the profile on the computer. You have to download the Oceanic with the, albeit cheaper now, cable to the pc to see your whole dive profile.
I love the ease of use, big display, two buttons, etc. I don't find the NDL limits to be out of line with the Vyper (compared to buddies), nor is the deco penalty that huge in comparison. It credits me for deep stops on the way up as well, if I blow my NDL and accrue a 2 minute <10 obligation I usually clear it before 40fsw on the way up. YMMV
