this subjective and depends.
I prefer ML soundlabs Mikko plugin. I prefer to craft my IR's to each amp and recording. Although the catalog for this plug in is new, so selection of speakers / cabs is smaller at this time. but essentially all the "classics" are there.
Ownhammer has good stuff too.
I don't mind the L6 cabs, but tend to use custom IR's.
although i'm a toontrack guy mostly, there are plenty of drum libraries out there with really good quality as well. its how you use it that really matters.
good luck.
