For me it's about trophies and success, and Barca's trio just won them treble last year and will probably win more than Real again this year.For me it's about the end product
Barca's trio is better than Real's man by man however you look at it. Messi is better than any of those three, and Suarez and Neymar are easily better than both Benzema and Bale, and they are at least on the same level as Ronaldo, many people will say that both of them are better than Ronaldo this year too. But even if you think that Ronaldo is better than any of them(which he obviously isn't), still any of Suarez, Messi and Neymar are on another level to Benzema and Bale.
Real Madrig scoring 10 goals against Vallecano and having the "end product" in their favour means absolutely nothing.
