Bibs are more comfortable for long rides and worse at every rest stop, and that is the entire decision.
Verdict
For rides over about an hour, bib shorts are more comfortable, because the straps hold the chamois exactly where it should be and there is no waistband compressing your stomach in a hunched position. Regular shorts win on one thing that matters a lot in practice: getting them off at a rest stop.
The comfort argument for bibs is mechanical. A waistband on a cycling short has to be tight enough to keep the shorts and the chamois in place, and it does that by squeezing your abdomen while you are folded forward over the bars. Straps over the shoulders do the same job with no pressure anywhere.
The counterargument is that a bib is a single garment attached to your shoulders, which means a full undress every time nature calls, usually including the jersey. Riders divide on this more or less permanently.

Your rides run past an hour, or you get lower back and stomach discomfort you have blamed on the saddle. The straps eliminate waistband pressure entirely and keep the chamois located through hours of pedalling, which is exactly where regular shorts start to shift. Most riders who switch do not switch back, the rest stop problem notwithstanding.

You commute, ride short distances, or stop often. No straps means no undressing, which sounds trivial until you are in a cafe toilet with a jersey over your head. They are also cooler in genuine heat and cheaper, and for rides under an hour the comfort difference is small.

No underwear under either one: the seams are what cause chafing and the chamois is designed against skin. Wash the shorts after every ride, since a damp chamois is how saddle sores start. Use chamois cream on long rides. Persistent saddle sores, numbness or pain that does not settle are signs of a fit problem, not a toughness problem, and numbness in particular should be taken seriously and discussed with a bike fitter or a doctor rather than ridden through.
No. The chamois is designed to sit against skin, and underwear adds seams and holds moisture, which is the combination that causes chafing and saddle sores. This applies equally to bibs and regular shorts.
For rides over about an hour, most riders find they are, because removing the waistband removes a genuine source of discomfort. For commuting and short rides the difference is small and the rest stop inconvenience is real.
Usually by removing the jersey or pulling the straps down under it, which is why so many riders complain about them. Some bibs have drop tails or magnetic clasps designed to make this easier, and they are worth looking for if it is a concern.
After every ride, without exception. A chamois that has been sweated into and left is the direct route to saddle sores and infections. Wash them cool and hang them to dry rather than tumbling, which degrades the pad and the elastic.
