I think this may be overlooking the primary benefit of IRCCloud: This is a service that makes it someone else's problem.

I ran a bouncer for a while, but honestly, it's really nice being able to pay these guys a few bucks and have them deal with it. It has a matching Android app, and the transition between my various machines is very smooth.

But really, the main reason I use them is because I don't have to mess with running a bouncer or using a console-based IRC client. It's one less piece of mental clutter for me.
