CFM is the important measure, but also think in terms of how fast the air is moving between the carb and the valves. If the air is moving briskly, usually from a smaller opening, response is likely to be crisper.
Unless you really are racing sizing a 4 barrel with small openings and only opening the second barrels when really needed probably makes a more pleasant driver.
Too much air going slow doesn't equal more power, it equals a pause while the motor catches up. On a mild motor I'd be really cautious about too much carb.
Of course someone else will have different ideas...

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
