yeah, i tend to go for a text by text basis (easier to do, and my notes are done more justice that way) and make some analytical synthesising comments in the conclusion, and in little mini paragraphs in between.
my teacher said that it doesn't really matter, but if you can synthesise, of course you will look better than someone who doesn't. also particularly say for texts n ways of thinking (individual and society) you can block off your boxes into the paradigms (economic, philosophical, religious, scientific etc etc)
