Im a BSAC Sports diver, half way to Dive Leader having done one short of 100 dives. No experience of PADI but my understanding its more expensive overall with a different approach to training. However I would echo the comments above, its the trainer that makes the difference regardless of the route you go down. Really makes the difference in your confidence IMO.
Most my dives in early days have been UK quarries and Farnes/St Abbs. However after doing a week liveaboard in the Red Sea and diving wrecks and coral reefs, diving in gloomy and green UK waters doesn’t appeal as much anymore.
