Which technology should we choose? MVC 5 or MVC Core ?

Hi,

My company planning to develop a new product soon.  I suggested them use MVC Core instead of MVC 5 as MVC Core is latest one and also Microsoft roadmap for MVC core is really good.

Just I wanted to confirm that Is there any applications developed and in production using MVC core?  If so, list them.  

And also please correct me if my recommendation is wrong.
