I've been using Linux for years, so I've got my opinions about distros. Why should the distribution a new user pick matter that much? They can easily switch if they don't like the first one they pick.
Well, IMO, a new user should pick a distribution that has different DE's available in it's repository. That makes switching and trying different DE's very easy. As opposed to some distros which are specifically tailored to only a specific or supported DE.
What happens then is that the new Linux user soon needs a newer version of some package and they have to add a third party repo to their stable system and after having done this a few times, soon an update from one of them will cause the install to be unbootable.
I've had a way better experience with desktop Linux when using a managed rolling release like Manjaro.
