Lego is ABS which is relitively expensive while most competing bricks are made from polystyrene.
The tolerence is the key thing though - we've got a reasonable selection of lego here as well as a few sets of Mega Blocks, Kreo and the odd chinese brand, and there's a huge difference in fit between brands with none coming close to Lego. Try watching your kid build something only to be unable to play with it because it keeps falling apart because the brick fit is sloppy
