*TLR; DR*: Depends on the DTLS server, normally it would pick the strongest (on security terms). Also, most of the nodes doesn't have enough memory space for them.
 
To be honest when I'm speaking about PSK and ECC what I'm really speaking are Cipher suites (But tinyDTLs only has one of each type). So, if a client supports both of them, he will send a list of the cipher suites to the server, and this one will pick the one its support (and if supports both, the one with best "metric").

In memory requirement,  If I remember well,  from the IoT-lab node list, only the M3 can compile with both of them.
