Try different ones out and learn which works best for what type of work?

Without getting too much into semantics, I would suspect that most individuals would have trouble classifying their "type of work" against an opaque set of "type of work" classifiers buried in a model.

He was suggesting that you try different models for the same thing and see which output you like best. It's tedious but at least you get an answer.
