Is there a good IRC client for Ubuntu?

I have recently outfitted my laptop with linux. (The HDD crashed and I used the Win7 for my gaming PC) Now that I am back into Adisc I want to get back to IRC but found out that mIRC and IceChat don't have versions for linux. If anyone can recommend a good irc client for linux, that would be spectacular. I am really looking forward to chatting it up with old friends.

XChat's a great client - I've used it before.
My choice is irssi. Scriptable and very customizable. Integrates well into minimalist and CLI environments nicely.

I use Arch myself, so I'm not familiar with Ubuntu, but the IRC clients aren't distro-specific so you might find this list of IRC clients on the Arch wiki helpful:

If you want something graphical, hexchat is probably what you want. It's a fork of xchat (which while stable, is no longer maintained).

Personally I use irssi, but if you want to go command line, may as well learn weechat at this point as it's on a pretty steady course to unseat irssi as the defacto standard on linux.

I still use Pidgin on all my systems, mostly a Win7 shop but also on my Debian laptop.
