you will probably want to use an op-amp integrator as your ramp generator, since the PIC wants a low-Z source for its analog inputs. Pic related, clock is ~95% duty cycle, 1V offset is to allow the (negating) integrator to zero. there's probably a better way to do that but I can't be arsed on a friday afternoon

4 cycles/instruction, for one thing. the W register, for another
I grant they are slightly cheaper than AVR and have slightly better peripheral options, sometimes
