Even then, the disadvantage is minor, as the difference between buffers is negligible until you're at world class levels, and several people have shown that you can successfully switch buffers later on if you want to. M2 doesn't commit you to DF for life. On the other hand, M2 gives a nicer and easier transition into 3style because the single move swap means you're already half-way to doing 3style with M exchanges.I also absolutely dissgree with saying M2 "sucks", since its speed is comparsble to that of Turbo and the only real disadvantage shows up only when you're transitioning into 3Style: DF as a buffer leads into slower algs.
Anyway, as with most speedsolving methods, there is a lot of subjectivity and many different opinions out there, so OP needs to do his own homework, evaluate the options he's been given, and choose for himself.
