When I had to make that choice, I took the Maggies. As many other pointed out, they require a beefy amplifier. I was running them with a Sim Audio W5 and it was a very good match. Today, I would add on my ESL (or quasi ESL for the Maggies...)selection the new series of QUAD 2805 and 2905. These are really superior to the Maggies and ML in every sense. They are the best speakers you could get in the mid frequencies and very easy to drive.
