There's a reason for that - outside of the composition itself it's because Prydz properly mixes his tracks (mixing is the practice of balancing and making adjustments to each individual sound & instrument so they all fit together), uses hardware instead of software, etc.
To be completely blunt, proper sound engineering is an art that's not always respected in mainstream EDM. I know because I've seen several studio sessions of professional EDM producers who have no clue what they're doing, so much that I've seen guys who don't even know what the most basic of tools are for mixing. There are literally guys who make a profession just being a mixing engineer and a lot of EDM producers think nothing of it, so when something in this medium is properly done it sounds particularly good. Deadmau5 is one of the best examples of a guy who really understands that art, there's a reason he has such a fancy studio with all that equipment, it's because he goes the extra mile for his tracks to sound the best, and it pays off.
