If mpv on Linux and MPC-HC on Windows, what is recommended on macOS?

It's nice to see that someone revived MPC-HC (again). For a while MPC-BE[1] was the alternative. I don't know how they compare today, but the latter is still great.

Agreed, Media player classic is the Winamp of video.

Ugh... for the life of me I still can't understand why you can't click to play pause in VLC. Probably once upon a time it was about dvd, but the number of played dvds compared to pirated mk4 is probably one to a billion.
