On a newer hardware, I'd go with Pop because it's more up-to-date with drivers (esp. nvidia) and linux kernel. In my case, linux kernel version did matter for me because I had a weird start-up issue that was fixed in latest kernels.
Open Upgrade Manager -> View (Third Menu) -> Linux Kernels
You can choose from the backported kernels from 18.10 and 19.04 ATM, guess the kernel from 19.10 will be availlable soon.
That way i got to undervolt my AMD GPU without a fuzz.
I install my graphics drivers (nvidia), go to the nvidia settings control panel, turn on full composition (run the desktop through the gpu) which enables vsync on the graphics card. I then go into general (settings) and set vsync to none, disabling cpu vsync. This makes Mint as smooth as butter. It also improves youtube playback quite a bit.
