PPL airfield choice question
The more important thing is the quality of the school.
I trained at Southend (EGMC) before it became busy again to PPL level, and at Stapleford to CPL level. Both offered their respective positives and negatives. At Southend, clubs were having you fly big, wide, airliner type circuits, you had a Tower and an Approach control, and lots of room. Good for keeping things simple. At Stapleford with its Radio service (no active control), you had to be more mindful of other traffic and be more flexible. Just a pair of examples there...I am sure others will have similar tales.
But really, the quality of the club and the actual training available should be your guiding light.
Good luck with the training and fly safe!
