on the early pics (and modern bottom of the range ones) it made sense to write in assembler, the chips were so small that the overhead of a compiler would have been unacceptable and the programs had to be fairly simple because that was all that would fit.

however with the PIC18 series (and even more so with the PIC24/DSPIC series) things have changed, memory is far less tight than it used to be and the instruction sets have been designed with C compilers at least somewhat in mind. C is quicker to write and far easier to read (provided its written cleanly rather than falling into the trap of using every dirty trick in the book) and you can still use ASM for special instructions or performance critical code.
