Rob Sherwood's work has focused on RX. Here's a summary and analysis I 
did about 5 years ago of ARRL Lab tests of selected rigs, including 
those that had been used in the recent WRTC. For two or more stations on 
the same band (CW, SSB, FT4/8), the major issue is phase noise.

The Elecraft K3 and K3S are, by far, the cleanest rigs and the best able 
to stand up to strong signals. It's my understanding that the current 
generation of Flex rigs are pretty clean on TX, but MAY have issues on 
RX in a multi-TX environment. They're working very well in multi-TX 
contesting, but these stations usually have BPFs in front of them. I 
haven't seen any feedback on how their RX would hold up with another TX 
on the same band. The limitation is the dynamic range of their A/D.

If I were looking for a mid-priced contesting rig, my first choice would 
be a used K3 or K3S.
