I'm mostly writing "high quality production code" - and for logic errors which can't be gracefully handled I find little to no difference between .unwrap() and .expect(). What I'm usually mostly concerned about is understanding where the error happens if the application crashes, and a stack trace is the best way to obtain this information - not the actual text message. From a crash report and a stack trace it's usually clear what happened, and I think using either a custom panic! call or except would only be helpful if more information about the current state of the program would be helpful to debug the issue (like "expected value to be between 127 and 255, but not 1234"). For errors that can be gracefully handled - sure, using ? is definitely preferred to any kind of panicking.
