Tmux vs screen

That is quite possibly the worst "VS" wiki I have ever seen. Where are the comparisons? Why should I want to use TMux over screen? What are the pros and cons?<p>What I learned from the article:<p>1. They use different licenses<p>2. TMux has a client/server architecture<p>3. One uses ctrl-a and the other uses ctrl-b as the control key<p>4. The goals for TMux performance is to be "relatively fast"

I've seen a few comparisons between tmux and screen around here and they've all been useless. Can someone around here who is familiar with both PLEASE do a write up?

Tmux is a client/server system and GNU Screen isn't? Really?<p>How does GNU Screen work then?
