I don't know about transparency film but for negative use Fuji pro portrait for contrasty light. But, if the light is flat, then the punch of consumer film will please the eye more, especially if you wish to sell or even give friends prints. Pro print film is often designed to allow Black to white detail (e.g. weddings dresses and Morning coats) in high contrast light. In low contrast light, like cloudy Great Britain and often in Japan, Pro fuji film can look horribly flat and muddy. Kodak, I think, offer some ultra emulsions in their pro range which address this problem but Fuji consumer film is cheap.
BTW I read in Chasseur d'image a very good french magazine that most French pros use Fuji sensia film (old pre digital days here) rather than Provia or Astia for normal work because, the shot is more important than the film. You don't want to worry about film costs, Digi users don't.
