Visually yes they are, and really apply more to 7u spacebars.

Though more importantly to me they have the added benefit of giving you slightly larger ctrl and alt keys, and makes the win key harder to hit by accident. For me that means 0 accidental win key presses when crouching, or since I play MMOs keyboard style, when I'm hitting an additional hotbar combi (i.e. alt+something).

And if I wanna rage quit, they give me a nice big alt key to alt F4 with XD
