I used to feel the same way, but then I was standing in a (short) global entry line and I watched people breeze right by that. Found out they were just using the free CBP app. Felt a little cheated, honestly.
Haven’t been doing as much international travel since second kid was born, so we didn’t get him global entry. Last trip we did I used the app instead. It was just as fast as global entry, possibly faster.
The only real reason to get global entry again now is for tsa ore check, and there are easier and cheaper ways to get that.
