The quality 12" would be more portable and not need a ladder to use, but would cost more.
That 16" tested on cloudy night is 1/3.14 wavefront error, which is better than 1/6 wave peak to valley. To quote the tester: "The gentleman who tested the mirror was impressed by the test results given the fact it was a machine configured mirror. He also indicated it was the second best 16" mirror he has ever tested."
