People say that beauty is an individual preference, but they are wRoNG. Beauty in a woman is very clearly defined as a waist to hip ratio of .7
Similarly, the curvature of a ukulele is similar to a woman's curvature. I suspect that God modeled the first woman, Lilith, after a ukulele. But I digress.
Keep this in mind: Measure middle inward curve and divide that by the bottom outward curve. The closer it is to .7 the more beautiful it is. Cutaway or non-cutaway is insignificant to asthetics.
Functionally speaking, get the cutaway.
