Who's goal was more difficult -- Bobby Zamora's or Xherdan Shaqiri's?

Both similar goals -- Bobby Zamora's chip goal versus West Bromwhich Albion for a 3-nil Queens Park Rangers lead and Xherdan Shaqiri's exquisite boot against Everton -- but which one was more difficult if not impressive?

Zamora was close to the edge of the box while Shaqiri was closer to the middle. While Zamora is left-footed, he managed to get the shot off against defender Joleon Lescott from the right wing. Shaqiri is left-footed as well but I think was in a better position for that goal. 

Regardless, both were spectacular.
