My T is only a few years older than me and when I started with her, she was maybe 3 years out of university and started working in that office right after. She's better than any of the T's I had to deal with before her. There were T's in the age of 30, 40, 50 and 60. And not one of them knew so much as her. Not one of them knew how to deal with me and my anxiety issues.
So older isn't always better. And you don't always get transference with every T of a certain age.
