Ubuntu was easier to use out of the box, especially for some hardware like Nvidia hardware in example. Also the software from its repository and the Kernel is not updated nearly as often as Ubuntu. All of this makes it harder to use for Gaming oriented people. Back then Debian users laughed at me (Ubuntu user back then) for using a “toy” distribution. But Debian was not a good option for me back then.

My point is, it does not matter if someone laughs at you. Just use the best option for you.

But where is the fun then? ;p On a more serous note, yes I agree. In most cases (probably all cases) there should be no need to get rid of zombie processes.
