The AVRs are nice, but those 32 registers aren't nearly as "general purpose" as Atmel would have you believe. They are a bit nicer than PICs, but they're also a bit more expensive and harder to find, and their "pin compatible ranges of parts" are not nearly so broad as the PICs. And they appear far less often at bargin prices on eBay. (and for some reason, there don't seem to be nearly as many cheap build it yourself programmers for the AVRs, although I can't see any reason why there shouldn't be...)
