I personally prefer the external RC as well.

For some reason, the Client-RC causes me to lag whenever a message or echo flies through on RC.

Whenever I accidentally hit the F6 button on iEra, I have to reconnect, because it severely effects my FPS.

Also, I dislike how Client-RC displays everything.
Chat, Trades, Reports, etc. It all populates in the same box, and there's no way to isolate it.
I prefer the tabs on the external RC.

This may be something that could be adjusted on our server; but it's another huge turn-off with Client-RC as of right now.
