The question of which is best really comes down to what you are going to be doing with the system. If you are gaming or normal usage there really isnt going to be much of a difference between the 1155 and the 2011 sockets performance. Now on applications where high memory bandwidth or extreme ends on PCI-e bandwidth are heavily multi-threaded jobs you might see a difference with the 2011 socket based boards and processors in performance.
So if you are doing something like video editing go with socket 2011 or if you are gaming or normal usage go with 1155.
