Well, technically speaking, the Maillard Reaction involves amino acids and a reducing sugar in the presence of heat. Carmelization is a similar process in that it is non-enzymatic browning. However, a piece of meat is not composed simply of protein. It also is loaded with blood. Blood contains glucose, which is a sugar, so the browning/searing of a steak is really a combination of the Maillard Reaction and carmelization.
My guess is that, technically speaking, the resultant flavor is probably due more to the Maillard reaction simply because there is more protein by weight than blood glucose.
However, not having studied the composition of meat (I'd rather be carnivarous and eat it!), I'm not sure what else is going on. For one point of interest, there is fat to contend with, which is neither a sugar or a protein. I can only conjecture that since fat is the result of a living body converting glucose for storage purposes and if one is on a diet, if the body requires more glucose than is being consumed, it takes the stored fat and reconverts it back to glucose. Maybe the heat is doing the same thing to the fat, I don't know! Again, I like the flavor that fat gives to meat (i.e. hamburger) but I don't particularly like eating pieces of fat.
My mother used to cut the browned rind off of steaks and swallow it whole, like a long snake! Ugh!
