I'm an instructor for one of the schools you mentioned Diana so I don't think I should post specifically about it. I can comment on San Diego and flying around the SW.
The flying is great with plenty of places within reach of SD, there's LA, Vegas, Phoenix, San Fran is only 4 or so hours away. If you like to fly around nice scenery then California is a much better place to fly than Florida. The major problem you'll find is that there are no JAA CPL schools local. The only schools that do the CPL are over in Florida so that could be an issue.
<<edit: It's somehwat off topic but I've often wondered WHY there is nothing West of the Florida Gulf coastline to do JAA CPL training. There IS Oxford at Phoenix, Arizona - but they are not dedicated to the usual modular market.>>
