I don't make my own fries, but frozen tots, fries, or onion rings come out really good to me. Steak fries, curly fries, and even orange fries. Well, it depends on what's in the bag, but even generic brands come out just fine. I just don't want to deal with a dedicated big daddy fryer with oil, so the airfryer and frozen junk food is good enough for me.
Some of the frozen jalapeno poppers are pretty good too, and I get those frozen taquitos for the kids. And breaded cheese sticks. Have a bag of breaded okra that I'm going to try soon.
Have leftover fries or tots from a restaurant? They come out really good too, in the airfryer. Better than baking in the oven. Last batch I did came out golden brown and crunchy, and better than what was served at the restaurant. You just can't overload the basket. If you have a lot to cook you need to do smaller batches, or dump and mix them up frequently. Spray oil in an aerosol can helps.
