@Maude, you sure do have some strong (and wrong!) opinions! 😂
I jest, of course! All very much each to their own with all these things.
The ergonomic carve, if done properly, is deeper than a top wood would cover. It would need to be an extremely thick piece of top wood for that to work, then the side profile would look odd as the top wood would be super thin over the cutout and ultra thick over the rest of the body.
That design is a bit of a compromise to ergonomics, for me I like the contrast, but even if I didn't, having played my custom ACG with a deep ergonomic cutout, the function far outweighs the aesthetics.
But, it's all very personal! No rights or wrongs etc.
