Those advocating for longer dive times and not wanting the computer to tell you to end your dive before you want to go... you can always set your computer in "gauge" mode and then dive as long as you like, or at least until you run out of air.
If you prefer an a less conservative computer only because it "allows" you to stay down longer than a Suunto, what happens when your computer tells you it's time to end your dive... but you don't want to? If you're going to rationalize ignoring a computer's advice (and that's all it is... just advice; the computer doesn't require you to do anything), why bother even having a computer? A watch and depth gauge combo will give you the same information, is much cheaper, and will never ask you to end your dive.
