If I am not mistaken, you have boiled this down to say, its up to the diver to choose for himself. And you have also said that for your diving, yoke works just as well, if not better than din.
But, you see, the guy came here asking for advice. Usually, that is because they do not have enough information/knowledge to decide for themselves. So far as I can tell, you have not given any information as to what different considerations to take into account to decide between yoke and din regs. Just that it is up to him.
Others, such as myself, are offering definite points to consider. For example, if you want to do tech dives outside your home area and therefore might need to borrow tanks from other tech divers. Or if you go to cave country and need to rent tanks. Or that fitting a din reg onto yoke tanks is trivial with an adapter whereas fitting a yoke reg to a din valve is not.
Do you think the above are valid or not? Also, are there other considerations you have in mind which make yoke regs more appealing? If so, what are they? Or are you saying that yoke regs are just as good because that is what you use?
