Remote Desktop Clients for Android

I looked up for remote desktop access clients for android, and found the following all seemed promising. I have installed 2X Client and it works pretty nicely to connect to my office desktop; the other ones promise better speed or interface, but I see no need to pay when the free app works fine. Recommended.
