A diving computer gives you PRECISION.
The fallacy of using dive tables for non-square profile diving is misinterpreted as a "margin of safety" when it is really not. It is instead a gross misapplication of dive tables designed for square profile diving.
If you dive a square profile with your dive tables, and you dive out to the limit of your NDL time, you have put yourself at the edge of DCS. In that case, it is better to utilize realistic, legitimate safety margins for your diving, like the following:
1) dive times will within your NDL limit
2) nitrox mixes that offgass N2 more efficiently
3) longer surface intervals
4) limits on the number of consecutive diving days with non-diving days to rest
5) extra hydration before and after diving
6) decreased exertion before, during, and after diving
Its a long list of things you can and should be doing to stay away from DCS exposure. And using your dive tables for your multilevel diving is probably a misapplication of the initial and primary intent of the tables, rather than a legitimate "margin of safety."
In my opinion.
