There isn’t a best distro that supports surface hardware. You have a to install a distro of your choosing for which there is a guide on the linux-surface github and then follow the guide.

There. Is. Not. A. Single. Browser. That. Values. Your. Privacy.

The biggest annoyance to me is how small the border around windows is. On Windows, I can grab anywhere around the edge of a window and resize it, including in both directions from the corners. In Linux, I need an electron microscope to find the edges, and the hand of god to find a corner.

This is a problem with the DE that you use and not linux in general. Gnome and KDE for example don’t have this issue. I’m guessing you’re using xfce?, since I had the same issue with it.
