Hi, and welcome to the wondreful and strange world of Linux/GNU.
First of all there is a differende between Linux and Windows as far as Win is a ready and done OS, while Linux consists om the distribution ie what’s under the hood (what make your system run) and what you see (the Desktop Environment; DE).
In Linux ypu’re free to combine them as you wish.
However if you’re a total noob, there are ready to go distros (the Linux version of an OS), and in the early days of your jurney I would recommend Deepin OS to start with, and if you aren’t content you can later switch to Endeavours version of Deepin when it is due,
Deepin is out of the box beutiful, and easy to use, and whil probably be faster than your current Win10, however Arch-based Deepin will be faster as the underaying system is lighter on resources.
My five cents says begin with Deepin OS and try it out, and then switch to the Arch based Endeavour when you begin to know a little more.
