Is the 58mm PF "Scientifically Optimal Size?"

What is your opinion of the 53mm vs the more popular 58mm basket? I've heard chat about the only difference being the ratio of diameter to depth of the basket, but my gut says the greater diameter-surface area is better? I wonder if the ratio of the diameter to depth on 58's is some "optimal" value, derived after a long period of hands-on testing, and that's why it exists as the most popular size? (And here I am, a 4 year user of a La Spaziale 53mm.)
