Did you just out rant me? No you didn't!!!
I will answer your question about Higuain being apprehensive. Basically, from the time he stepped a foot in Madrid, he has had to fight for his place at every stag for some odd reason. Every season he is dropped, only to regain his spot because he is a goal scorer and one hell of a machine. If it wasn't for the fans and his impeccable work he would have been destroyed and out of the club, but the kid as you said has confidence that can drown Benzema. But he surely is insecure about his position.
I didn't say Higuain has better chemistry with Ronaldo, I said Higuain had to conform to Ronaldo for them to get a long. Benzema is doing the same, laying the ball off to Ronaldo along with Ozil at every single turn. Ozil and Benzema are always looking out for Ronaldo, they just don't dare piss off the alpha dog in the team. Higuain on the other hand is his own entity yet he allowed Ronaldo enough space for them both to score tons of goals.
Benzema has two things over Higuain. His short passing is better (sick at one twos), and his dribbling in tight spaces (instant momentum). Higuain however, has often provided aerial crosses and low crosses to Ronaldo. In CL, Benzema > Higuain. Keep in mind, better players are not necessarily better performers. Also keep in mind that, we have played better football lately because Ronaldo decided to play better football. He was as selfish as they came, last 20 games he has been
I am still skeptical about Benzema, we have not faced a team that has required us to put tons of defensive effort from the front, which I will be really happy to see Benzema excel at while keeps on scoring.
Whether we play better football is subjective, with Higuain we don't take any prisoners, with Benzema we can play tiki taka. Plus I think you are getting a little carried away, you forgot that Higuain also plays intricate passing inside the box and you also forget that Higuain's one and only downfall was that he is so shit at holding the ball but he was improving before his injury. You also have to factor in Ozil becoming so freaking awesome it helps Benzema. I say it again, Ronaldo is playing more collectively.
I am on the phone, so I will end this here because I lost my train of thought.I will wait for your reply.
