I'd recommend against starting with "Against Method". Instead, go directly for the 'sequel' both to Feyerabend's "Against Method" and to two paper/essay collections (both published in 1976, two years after his death) that essentially originated from Lakatos, although they contain numerous contributions, among others by Feyerabend, "Method and Appraisal in the Physical Sciences: The Critical Background to Modern Science 1800–1905" (edited Colin Howson) and "Method and Appraisal in Economics" (edited by Spiro J. Latsis), namely, "For and Against Method: Including Lakatos's Lectures on Scientific Method and the Lakatos-Feyerabend Correspondence" 'by' both Imre Lakatos AND Paul Feyerabend, which Matteo Motterlini painstakingly assembled from the drafts for the book (which Lakatos and Feyerabend both wanted to produce, but which never produced a finished result in their lifetimes, primarily due to Lakatos' unexpected death in 1974.)

I say this because of what I personally like to think of as 'paraduality' in science which both Lakatos and Feyerabend discuss & address, but from 'opposite' ends. I put "opposite" in single quotes here because I find too difficult to phrase the point I wish to make, so I can only allude to it: Reading Feyerabend without reading Lakatos carries with it the same (and not just similar or the opposite) problems as reading Lakatos without Feyerabend does - and vice versa. The same applies to science itself, which kind of sums up the problem both of them approached, from 'different' sides.

I thus find it rather helpful to read the entire matter chronologically 'backwards', starting with 'For and Against Method' and then going back from there.
