I would recommend to learn an advanced edge method first as it will improve a larger fraction of the pieces you have to solve. M2 is a great method, however, if you think about learning 3-style later, I would prefer Orozco with UF as buffer and BU as helper. It is very similar to M2 and by learning this you already know 24 of 440 3-style algs. Most top BLDers agree that UF/UFR is one of the best buffer combinations. So UFR is highly recommended in this case.
