I used both for years but always preferred weechat with the nicklist enabled and at the top, so that it didn’t break urls or selecting multi-line text. Although the nicklist feature is moot for huge irc channels the ui and user experience is overall better with weechat in my opinion.

Alternatively there is weechat. I haven’t tried them back to back so I can’t tell you which one I like better
