I think that silicone is over-rated, since the hose I listed is OEM rated, and silicone only has limited tolerance to gasoline and oil, which cant help but be present in an engine bay...
Also, I happen to like black, and to me a bunch of blue or red silicone hoses scream rice-a-rony a little too much. Maybe If I had a GT42R to back it up?
I say, it's your money. If you think that silicone hoses are THAT much better, then go get em! The reason I posted my advice is that the same advice was given to me earlier by Kevin Landers when I needed help.
