i thought CMMRS was pretty good. hell, i still can recall the ridiculous pictures (rocky mountain spotted fever, coxiella burnetti, etc) and even though a strong grounding in micro + FA could possibly suffice for the student looking for a good (perhaps not spectacular) score, i would suggest CMMRS. For me at least, a good vs spectacular score comes down to my ability to make differentials very quickly as I read the question stem - if i can do this, >95% of the time I can get the question right. Doing CMMRS (though dense) helped me put things together in a way that I could easily recall. It was much easier for me to recall some fact or picture in CMMRS than the blurb in FA, but that is just me. I didnt read all of CMMRS either though. I stopped like halfway through the parasites section i think and im sure that didnt hurt me in anyway. definitely go with what works for you - CMMRS helped things stick with me so I stuck with it. If this is not the case for you, look for some other sources, and there are definitely a lot of them out there.
