I'm going to disagree with you there. I've been using a Suunto (still use my D4 that I bought in 2008) for much longer than most people that bash Suuntos, so my opinion is based on a lot of direct experience. My RMV is pretty low, usually between 0.36 and 0.40 cu ft/min, and on typical dives my Suunto gives me enough bottom time to effectively use most of my available gas (so I'm finishing a typical dive with around 700 psi.)
If I was given additional bottom time by a less conservative computer, I would need to improve my RMV to take advantage.
My D4 has spent 500 hours underwater with me (with zero problems) and I've had zero DCS incidents, which, for me, is the most important feature of a dive computer.
