ADTs turned into classes, when it appeared that there was more research funding available.

I dont't think Abstract Datatypes are completetly outdated. Maybe they 
have proven not to be usefull as _fundamental principle_ but that does 
not mean that some proplems would be solved elegantly and compact or 
whatever your criterea for Good Software is with ADT's.

You have to investigate your problem, look at what tools you have and 
what you like, and then make your decission. It's never good to use 
always the same, only out of personal sympathy or habbit nor is it good 
to expect a method to work for every situation (... equally good).
