McDonalds or KFC

Don't have KFC where I live and don't eat in much fast food places (My family's culture is very food based and it's all delicious) so if I had to choose I would say McDonalds but don't even eat it that often
 
Mcdonalds fries are good, KFC Zinger burgers are nice, both equally good
 
KFC, I agree that the fries are bad at times. Too soggy, unsalted etc...

But on the contrary depending on where you live on Earth you may have such as pepsi cups which you can then refill how many times you want during your stay at your local KFC establishment. AFK a good 45 minutes extra after eating for free stuff.
