It's a mix of research from the web (and I don't mean copy & paste), questions I and others have asked, and my own experience with Nim. This is not simply copy/paste. The rest of the comment I won't even bother to address as you sound like a troll.
Some people prefer Nim because of small things like syntax. However Go is much more popular. I will do more research on this subject and see if I can list the differences in detail. However any such list could be soon made redundant when Go 2 comes out.
