I'm fairly new to this game, although I do have some prior expierience from way back, I didn't have my own gear at the time.
I like it when things work for me and in anything I do (mountain biking, climbing, photography, etc.), I try different things until I find what works for me. I am also in the Navy so using back-ups are just part of the way I do things. That's what working for the Department of Redundancy Department does to you!
Anyway, I have a Suunto Cobra 2 console with the add-on compass so I have everything in one place. I route the hose under my left arm and through the left BC shoulder strap and then clip it to a retractor on my right shoulder strap D-ring. As stated above, I have everything at my fingertips and the compas is in a good place for me when I navigate although sometimes I unclip it for this. I can also grab it and operate it with either hand.
I also dive with a Suunto D4 watch as well (redundancy right?) when I take off the watch to put my arms in my wetsuit I put it back on upside down so the face is under my wrist. Now, when I grab my console with my left hand, I have both side by side to compare.
Although during the dive, I occasionally just look at the watch, ususally when I know I'm close to my max depth, most of the time I am grabbing the console.
Considering the guys I dive with and my low air consumption, I usually don't even come close to getting low on air during a dive, but I still want to know the numbers as I go and think it builds a good habit. Having the console makes it easy for me to have it all in one place.
As for ruling out Suunto, that is your choice, but don't do it just because of any of the squabbling you've heard here. Dive one, dive with someone who has one or ask someone you trust who dives with one. I spent a good bit of time reading through both my manuals and Suunto's explaination of their RGBM.
From what I read and have expierienced, their 'conservativeness' only kicks in when you do something to warrant it like ascending too fast for too long or blowing through a manditory safety stop, but not for skipping a reccommended safety stop. Do this frequently enough on consecutive dives and you should see a slightly shorter NDL which you earned by putting yourself at a higher risk of DCS due to your actions. Most of their newer models including at least the D4, D9, Cobra 2 and Cobra 3 allow you to mitigate the penalties with a lower RGBM setting if you feel you are more expierienced or have a lower risk of DCS.
I have had no reason to change the RGBM settings on my computers and have had no problems with losing dive time. My buddies run low on air (even with Steel 100s) long before I come close to my NDLs - even on a three dive day.
I'm not saying you should buy a Suunto, just saying don't rule them out because of forum gossip. Decide for yourself. Hope this helps.
