Judging by the screenshots it does look quite similar, nice. Do you know whether it works well on mobile? That's one of the main selling points for many users. The tmux+ssh user experience is not that great on mobile :)

Well, for quassel, there's also a mobile app. On the Play Store the beta version is quite neat, and the F-Droid version. The normal Play Store version is from 2013, though.

I - maintainer of QuasselDroid - am currently working on a next version, though, which will take another few months.

For iOS, though, quassel-webserver is the best you'll be able to get, and it's quite meh on mobile.

The weechat android experience is amazing. I actually switched to weechat from irssi and irssi connectbot specifically for it.

Quassel did not have nearly as nice a client for mobile and I really prefer terminal based clients on non-mobile platforms.

Quassel has QuasselDroid for mobile, and a plugin for irssi for PC.

So, it's comparable.

I've since moved to IRCCloud, but when I tried Weechat Android it was very rough around the edges.

I hear it has improved significantly in the last year or so, development has picked up speed again. And I say that working on the competition ;)
