I d tend to agree that Long Beach is the best but then I m biased! But surely the school you chose might be a more important factor?
My thinking is that if I went to a school in California the airspace is busy which is similar to the UK, compared to the Florida schools.
The school I've seen at Long Beach is UKFT and the school at Gillespie Field is one that I'm not allowed to mention on PPRUNE
