more advice needed !! - Which teacher is better for the advanced student

[chopinlover2012]

Teacher A:
Having a doctoral degree in piano performance, is an excellent pianist, but with limited teaching experience, age at his early 30's.

Teacher B:
Having an associate diploma, no university education background, lots teaching experience but without performance experience, age at his early 80's.

Their credentials shouldn't matter.

Have a couple lessons with both and decide who is better yourself.

Within very broad limits, none of the items you mention -- degrees, performance, age -- make much difference.  The question is which one can help you become the best pianist you can be?  And the only way to find out is to take some lessons -- several -- with each of them.

There's something to be learnt from everyone.  The question is how much and what level you're currently at.

True, though sometimes that something is "Run!!!".

I would be less concerned about formal qualifications, experience and even performing abilities (within reason).  There are plenty of people who are very good indeed at something, but are not good teachers. And some people have taught for a long time without actually being particularly good at it.

As an advanced student, you should have a discussion with each of them about their teaching philosophy, what they think they can do for you and what their (and your) expectations are. Then go with the one that feels right.

I agree that I might try both  - and asking questions is good.
If you can identify your gap of learning - where you need to go next -
see if they can help you right away with it
