Underwire bras are not dangerous. However some are poorly made and uncomfortable.
Playtex bras offer both underwire and and non bras. It depends on personal preference.
No they do not.
It depends on what size cup you have. Most people agree that if you have a C-cup or bigger, you need underwire. A great alternative to underwire is to get fit for a custom fitted bra, which replaces the underwire with a second layer of stiff fabric, supporting the breast from underneath. These bras will last up to 4 times longer than an underwire bra.
Several manufacturers carry maternity bras with underwire such as Playtex, Leading Lady, Anita, Bella Materna and Lunaire.
Underwire bras were invented in the 1930s by Howard Hughes, who was inspired by the design of the cantilever bridge. The underwire is used to provide additional support and shape to the bra cups.

Men find underwire bras as uncomfortable as anybody else who wears them. However, like most people they may enjoy the extra support and lift that it gives boobs.
underwire gives a lot more support, but if you are more flat chested soft cups are more comfortable x
It depends on the woman and the underwire bra. Some are painful and the wire escapes the bra and pokes. Others say they are quite comfortable.
There are not necessarily different cuts of sports bras. However, some have underwire or different thickness in the straps.
