Should I use what the professor says to me in the email as a material to write in the SOP? So a professor agree to accept me to his lab. I guess that I should write this down on my SOP to increase my chance. The question is: should I use what he said as a material to write in my SOP?

Below is my draft:


  I have contacted him, and within an hour I got his reply: “You would be a terrific addition to our group!”. He said that I'm “correct that more insight is needed on the relation between A and B”. The lab is currently working to formulate a C theory. He sent me a paper he wrote with his student, XYZ, to illustrate one of the approaches. I have suggested some ways to expand the work during my discussions with the professor.


One feedback for this:


  Very awkward. I'd delete. At the very least rephrase. It feels like a brain dump. He already knows you'd a be a great addition, no need to state it here...It's also a bit presumptuous to me that you're so comfortable critique a professor and such. Could be another bias of mine?


I'm speechless. This is the only paragraph that will make me stand out from the others, yet it is presumptuous? Is this the culture problem or is it just me? I can't see why this is presumptuous.
Yes, you should delete that. It doesn't add value. You should mention that you were accepted and what you plan to do, but there is no need to include the following smalltalk. Getting the Prof to say "You would be a terrific addition to our group!" is politeness not an achievement in itself. An achievement would be if he said that after you worked there for a month.

Also, I don't think that is the only thing that makes you stand out. The Prof surely has reasons why he accepted you, he doesn't accept at random. Maybe you could ask him what led to that decision.

How is the following:

Professor X wholeheartedly accepted me to work on the relation between 
A and B, which will help to formulate C theory. I very much look forward
to work on this topic because ...
