Razer laptops come with the latest and greatest in terms of GPU/CPUs, plus they usually feature things like high-refresh displays, full RGB keyboards etc. They're still overpriced, mind you - since you can find comparable laptops for literally half the price - but at least they have the powerful hardware in them to somewhat justify their steep pricing. Similarly to Apple though, their pricetags are heavily inflated by the Razer branding.

Can't comment on the Surface, never looked into them much.
