I think it's ridiculous for him to insist that you buy new gear. Maybe it's not exactly what he would have picked, but so long as you are trained for it and it's well maintained, then tough. Part of the reason there are so many choices in dive gear is because just one thing isn't going to work for everyone. You should politely tell him thank you for the advice, but you are happy with your current set up. If he refuses to dive with you because of it, that's his problem.
I know I'm a newbie and I would welcome advice or suggestions. Heck, once I know more about it, I'll even welcome enthusiastic discussions about the merits of A vs B. But if someone point blank told me my gear was crap and I *need* to buy XYZ, I'd tell them to stuff it.
ETA: Unless he's offering to buy you all this new gear... ^_~
