This is a good question. Some user made a good list in superuser https://superuser.com/questions/236158/tmux-vs-screen.

For me, it's because it's more common to use tmux and you can find from legacy configs to modern ones. So, for me, that I have not studied IT (and now I work as a programmer) it's essential to find basic configurations all over the place to have an anchor.

But, as always... Use whichever works for you. Don't think in the "best" or the "most efficient" which is just youtube propaganda. Use whichever works for you and makes you feel like home. If that's 98's microsoft word... then embrace it and be proud to have an opinion.
