Standard Aspect Ratio vs. Wide Screen Monitors?

I'm trying to garner an informal consensus or opinions of SW users on Standard Aspect Ratio (4:3) vs. Wide Screen (16:9) Monitors in a dual monitor application.  It is probably a function of size and what you are accustom to and parts you are modeling, i.e. more square items vs. long skinny.  I would like to hear experiences, pro/cons etc.  Reference - 20 to 21" Standard and 23 to24" Wide Screen.

Kind regards,
