Two, the nature of the work, Watson's engaged in the retail industry, KFC is the catering industry. The direction of development in the future is not the same.
Three, work intensity, KFC work intensity and pressure is much higher than Watson's, but also learned more than Watson's. But the personal time of Watson's is relatively high. But Watson's personal time is relatively more, KFC basically all of their own energy to dedicate to it, so it is more suitable for fresh graduates or young people.
Four, development potential, due to Watson's faster development, more room for advancement. KFC has a lot of gray sufficient room for appreciation.
The above is my understanding of the two companies, just for reference.
