In my opinion:

What do people like best about McDonald's and KFC now?

What do you dislike most about the taste of food, the form of fast food, service and business hours

?

advertising (everyone hates it). And the food quality of KFC

McDonald's is still good. KFC is much worse. The quality of KFC is still uncertain. I remember a few years ago, there was something circulating on the Internet about KFC's mutant chicken. I also saw it, and it was really disgusting. There is something wrong with hamburgers, too. Some people eat bugs in them. I dare not eat any more now.

as for McDonald's, I prefer it. There are more kinds in it than in KFC. There are big hamburgers and small hamburgers, which are more in line with everyone's needs. And there are almost no quality problems. But eating too much of that meat is always not good.
