If not, then the stationary pictures this camera takes would be better than those of a DSLR device. The resolution of a 35 mm. film is about 20 megapixels.
Define 'better.' What are you after? Perfect sharpness and high resolution? Don't shoot 35mm pinhole. Do you want to experiement with a different sort of 'look' or perspective? Then give it a try.
Judge for yourself.

Joe mentioned the fact that the camera will need to stay very very still since the exposures are generally at
least a few seconds (full sunlight, depending on film speed or ISO) and if you're working indoors, then a few minutes up to a few hours.
This exposure was 7 hours long - the only lights being the Christmas lights on the tree.

The other thing that relates to this is if you were thinking of doing portraits (as you mention in your title), then your models will also have to sit very very still, unless you want some motion blur, which I think actually could make for a more interesting portrait. This exposure was, iirc, 2-3 seconds.
