I agree with Sir George (but then I'm Barton trained as well). In my book, short grass runways and an uncontrolled environment trump 'big airport' facilities every time for ab initio training. You want to do another circuit 'cause you ot your instructor think it's a good idea? Just do it! At Scouseport it will be traffic dependant.
When I learned I visited EGCC and EGGP as well as other conrolled fields such as Blackpool. That kept the RT professional. Bur remember that you are learning to fly and the radio is NOT a primary fight control. These days I fly from EGGP and enjoy the professionalism of the RT as I go in and out. But that's the icing on the cake.
First - learn to fly! Barton will make you a better stick & rudder pilot with its short runways and self-reliance on positioning. Do the 'big airport' stuff later.
