If you were looking for training I think my advise would be BPL, the three runways have got to help with crosswind issues. It's very GA friendly has all the necessary lights, beacons and ILS's you need. Plenty of schools to choose from and easy access - LPL can be a real ****** to get to sometimes ( though that might just be my driving )And loadsa empty space and fields and things to play over.
Really they don't seem to have a great deal of difference for a PPL holder, but when the GA compound closes for the night it costs a damn fortune to get outa the place! That may be different for residents tho.
I think for me it would be where you tend to fly - if you go southbound mainly - go LPL - vice versa BPL. Generally both pretty good airports for GA.
