You bring up a good point: tailor the height of your workbench to your own specific size and needs.
My woodworking benches are 34-1/2" and 35-1/2", the latter being as tall as I'd want, at 5'7". These are heavily constructed or heavily laden; the smallest has (2) 60-lb lead pigs, for ballast, plus cases of fasteners and tool storage.
But my modeling bench is closer to table height, where I can sit in a comfortable desk chair.
It's a portable ~2'x4' building board top that I can secure to a heavy, metal, welding table, or move out of the way, when it is not needed; clamped to the table, it's rock-solid.
For very large work pieces, I've setup extra-low benches in order to bring the project to comfortable working height. I would never be satisfied with a bench which did not provide a solid, stable platform.
