They're heavy (-ish) but I can honestly say, I have over 3K loaded touring miles (on paved and gravel) on a pair of Marathon Plus 700x42 with ZERO punctures.
I advise that you be sure that you really want a very heavy and very stiff tire before you go for the Marathon Plus. To say it is heavy would be an understatement. They are literally twice the weight of some acceptable tires or even a bit more. They are very long wearing, but they also have a very stiff sidewall that I find impacts ride quality substantially.
They are extremely long wearing and puncture resistant though. So if you are an avoid flats at all costs type rider they might be for you particularly if you are not expecting a lively ride feel.
If you are like a supple flexible sidewall with a nice lively ride feel, I'd avoid them. I hated them enough that I took them off and sold them after a few hundred miles. Some folks think they are wonderful. So figure out which category you are in before saddling yourself with a set.
