I'm using Elementary, and I really like it so far. It's based on Ubuntu, and the standout things for me were:

1. Gets out of your way really fast - very little config and setup to do.

2. Clean UI - very macOS inspired, so they try and get rid of everything unnecessary. To the point where it doesn't feel like a normal Linux distro with knobs all over the place.

3. Excellent built in terminal - can't stress this enough - the built in Terminal on Ubuntu is very barebones - the Elementary terminal feels really polished and had everything I wanted coming over from macOS.

4. HiDpi support - you haven't mentioned what you monitor is, but Elementary handles retina and 4K displays well straight out of the box.

5. Ubuntu based, so pretty much everything that works there works here, apt is available for everything you need to install.
