Thank you all for replies!

Yes, I agree that both should be reported (even if the main effects are non-significant)!
And the interaction is the most-est important-est

I also agree that how they are reported is more to do with style than stats!
Has anyone ever been confronted about this, with the other person saying that the only correct way to report these results is to start with the interactions and then move on to the main effects?
