Well, actually I can use my 250 exposure film back and get 250 frames without reloading.

The equivalent in medium format would be a 70mm back.

Advantages for 35mm are motor drives, fast lenses, lens options, cost of film, cost of equipment, size and handling.

Sports/action photography, travel, lower end are all areas where 35mm has the advantage.
