I used to use Kodak for black and white, but the fact is that Ilford is now much better. When I shoot black and white film, it's Pan F 50. Stunning results, considering it's not slide film. I like the Fuji as well, though the Astia is usually what I end up using for 35mm scenery and trips(looks more like I remember it than a painting effect with Velvia).http://www.timparkin.co.uk/system/assets/1319
Here are four of the main versions together.
Pro160 is notable as it is nearly perfectly color matched to how our eyes see things. Yes, it's that dull and washed out, but high contrast as well. But that's how our poor eyes actually see things most of the time. I'd not recommend it for scenery, though, since most people are used to ultra-high saturation pictures thanks to decades of contrasty film.(the sky isn't ever really bright lapis blue, for instance)
But it is good for city and dawn/dusk type work(IMO) where you want the colors to look a bit more stark and under-saturated or exactly like our eyes tend to see things in that sort of situation. I find it too muted, though, for trips, so I usually use the Astia.
Provia kind of doesn't really do anything for me for some reason - it looks OK, nothing more.
I guess I'm a bit sick of the Velvia Christmas Tree green and red look, especially since 90% of what I shoot in color is in the evening or early morning. You can plainly see how over-saturated Velvia is for the time of day. Almost like instant in-camera HDR. But you can see why it's a favorite of scenery and similar work or anything that is intended to go in a magazine or on a poster. Because it looks bigger and brighter than life. Almost like a lithograph or painting.http://www.maremmaphoto.it/filmtest.eng.html
Here is a comparison to the older Kodak films for reference.
