What are the differences between rdesktop and xfreerdp?

rdesktop and xfreerdp are both linux clients for RDP. However from their respective websites it is not clear what advantages/drawbacks of using one over other are there. I found one post , which indicated that xfreerdp has more features than rdesktop. * But what are these extra features? * How is the performance (or responsiveness) and clipboard support in both of them? I am looking forward to use a RDP client (on Linux Mint 17) to connect to few Windows computers (Win 7 and 8) and linux servers running xrdp.
