give one reason why a lap flange and stub end would be used instead of a weld neck flange?

One common reason is because of cost. If you need to use a very expensive or hard to get metal for the pipe then the backing flange can be carbon steel like astm a105.

They are used in piping systems with critical wall thickness requirements.
