Depends on a few variables. What result do you expect. Do you want high color saturation or do you prefer something a bit more muted? Will you be using a custom photo finisher or a local 1 hour mini-lab? Custom photo finishers are more likely to get you good results from the higher end Kodak and Fuji films. The local mini-lab may not have the best trained operators around, and you'll probably get best results from something like the more common Kodak Gold films.
For high color saturation Kodak offers the Portra VC line of films. For a more muted color pallette, choose the Portra NC line. Fuji makes equivalent color print films with a slightly different pallette. You'll probably want to try a few and settle on the one that suits your vision best. All of these films are top quality materials, so you won't go wrong with any of them. There is of course, the option of using transparency films. Having prints made from transparencies today is technologically less difficult than in the pre-digital age, but finding a place that offers the service at a reasonable cost may be daunting. The advantage, of course, is that you can tell if the colors of the print match the colors recorded by the medium with a simple eyeball comparison. Other than that, transparency films offer very limited latitude compared to negative films, making it often difficult to capture both highlight and shadow details in the same frame.
