LEP vs. LHC for Higgs production? Now that we know the mass of the Higgs boson, which system would be better for the production of Higgs bosons, the LEP ramped up or the LHC?

LHC was designed as a discovery machine, whereas LEP was designed as a precision machine that would clarify the discoveries of SPS, the previous hadron collider at CERN. 
I think it was Feynman who said , I paraphrase, "when you want to see what  a watch is made out of you do not throw a watch on another watch and count the wheels, you use a screw driver" comparing the lepton interaction as  a screwdriver.
LEP delivered the numbers that established the standard model to accuracies inaccessible to hadron colliders. That is why   the next collider planned is the ILC, the International Linear Collider.
LEP  in its circular tunnel was working at the limits of the radiation emitted due to the angular acceleration of the electrons and positrons. It had reached a point where a paper for an 114GeV Higgs was proposed based on three events. A machine that will deliver accuracy of interaction parameters needs much higher numbers than this.  Linear accelerators lose much less energy and will be more effective and accurate at the same center of mass energy, because energy loss degrades the beams.
