Table Selection Strategy for 6 max NL

[excession]

It's better for short term $$$ and teaches you multi-tabling skills.

It's worse for learning - why not compromise and play 2-3 tables?

For example if you play 6 max and have PAHUD up it isn't that hard to get good reads on 10 opponents - only one more than if you were playing 1 full ring table - also by mutitabling you avoid the boredom (and itchy fingers) of a dry spell of cards more often..
