Reply to Comparison of 2 Similar DJ/Producers, One hated...One Not so much

Ok so im going through my music library, and I notice that David Guetta and Alex Gaudinos sound are essentially identical. Of course there is plenty of hate going around for Guetta but not much for Gaudino.... So i ask your opinion why do you believe? Ive noticed that Guetta only uses cheesy pop singers... Nikki Minaj, Chris Brown, Will i am, etc... where as Gaudino uses lesser known European singers, some with a background in house music. That could be one reason. Your thoughts?
