Difficult to answer.
Personally, I think for library construction Stratagene's system
works best. I am using libraries constructed in HybriZAP with the
Y190 reporterstrain and pGBT-9 bait vector sold by Clontech. In my
hands this combination gives the best efficiencies during
So taking bits and pieces from different places is no bad idea really.

Good luck
