The main difference in my experience is that the Pahoehoes last much better and are not "sticky" to the touch in the same way as the silicone white strings. I think the sound is marginally better with the silicones, but the feel and durability of the Pahoehoes make them a no-brainer, for me. YMMV, naturally

The feel and tension is better than the standard white strings, some people say the sound is more fretless like than the upright sound of the white strings, personally they sound very similar but I'm going from memory as opposed to a direct comparison.
Definitely worth a try though
