I personally think the MX Master 3 is pretty ugly compared to a Magic Mouse. I've never used one but generally dislike mice that are that big.

I don't think I have ever cared about how my mouse looks (or how my laptop looks for that matter; it sits at home where no one will see it).

Something you use 8 hours a day should first of all be pleasant to use and reduce the risk of long term damage to your wrist (carpal tunnel syndrome or similar).

Everyone has different priorities.

I've never found the Magic Mouse uncomfortable to use. I generally use a trackpad anyway. I value that it's portable, looks nice, and works great with OS X. To each their own.
