I learnt to dive via BSAC, mainly because MIL is a instructor.
No point in going into a BSAC/PADI debate, but I found bsac method very thorough and gave me confidence before I commited to deeper stuff and the sea etc. I learnt in a winter diving in UK quarries obviously using a dry suit, etc. So when I did my first dive in the Red sea it felt like a piece of cake in comparison! So if you can learn in the UK will give you a lot of skills but this takes time.
My other 2p’s worth is regardless how you learn is not to rush things through, and get the basics right like bouyancy and been familiar with your kit and also if you can dive with the same buddy as I felt that helped a lot.
