I'll assume you meant to say you "don't see why anyone wouldn't want there server to be linux based" :)

I've used both PHP and ASP(vbscript) extensively. Though I have used mostly ASP on ecommerce projects, that was a decision I had no input on and had to do with some back-end issues unrelated to e-commerce in general.

Assuming that's the comparison you're making (you don't mention any linux-based alternative to ASP), the true believers on both sides will give you a loud argument for whatever they prefer. Purely on an ease of development basis, I don't really have much of a preference.

For E-commerce specifically... I don't see why it would be easier. CC Processor support?
