Antti has a good point, if you want to fly in mountainous terrain it makes sense to learn there. If this is less of a factor for you, then . . .
Undoubtedly, though, YOU are the one who will make a difference for you. Flying helis is not a team sport and it's not a race. It's probably one of the most individual pursuits upon which you may embark. Think about what YOU want out of it and apply YOURself to it. Do this ALL of the time throughout your career. Keep a 'can do' attitude and get ready for a whole pile of 'No thankses' from many people you will approach for a job.
When you have a couple of thousand hours under your belt you probably won't care much where you learned to fly, and no one else will either to be honest. At that stage your actual flying experience to date will be the determining factor in what your immediate future will bring you. Your recollection of your flying school will be that you felt you got value for your money and had a pretty good time getting that value or it will be that you didn't.
Enjoy your time in the air, regardless of where it happens to be.
