I’m looking for an IRC client for OS X. I’ve run acros several but I’m not sure which will fit my needs.

Here are the current candidates:

• Colloquy
• Irssix
• Ircle (gotta love that name)
• X-Chat Aqua (A port of the popular Linux IRC client)

I’m leaning toward X-Chat Aqua, but would like to hear other suggestions.

Thoughts?
