Ask HN: Which is better tmux or screen?

Before you go on pointing me to archives or asking me to google understand that I have done that. The reason for asking is all the comparisons are by now old. I ask now because both might have progressed a long way. I personally use tmux but am not a pro user. I want to know if there is something that tmux has that screen doesn't have or vice versa. I would also like to know which is more light weight, more configurable.

Also I would really like to know the scenario of how you use either.

Thanks,

AM
