I'll be off to Hong Kong in 4 weeks or so and plan to shoot the skyline from across Victoria harbor. I'm wondering what (120 size) color film give me the most impressive results. Of course, impressive is very subjective so I'll leave it up to you to define. I will shoot both daytime, sunset, and night shots of the skyline, all on a tripod. I'm a newcomer to film so dont have much time to experiment and determine what I like best. How would you rate the following films for the job:

Reala 100
Porta (400&800)
Ektar 100

I dont know if the slide film can handle the dynamic range of these scene. Those buildings are lit up pretty bright at night while the night is quite dark.

Camera will be a Fuji GA645.
