Actually, what should I care if another likes PIC or Zilog, or any other lesser uC. I'm just pullin your string.
However, seriously, if you're using a uC that has the resources and architecture to support C, I'd recommend doing it. Programming is more productive and code is more readable. Yes, I've programmed in assembly, too, but I get more done in C. Unless there is a compelling reason to use assembly, but it is also possible to use inline assembly in C.
