What does "good" mean? I'd expect the variations due to power or temperature would be easy to measure. Delay through classic CMOS is linear with absolute temperature and inverse linear with supply voltage. The classic way to get time-nuts level noise on FPGA outputs is to wiggle a nearby pin. That shouldn't be a problem with a dedicated PIC but would probably show up if you are generating multiple frequencies. -- These are my opinions.
