What forge marks are on the upper receivers nowadays for the 6920?

My most recent 6921 (bought it earlier this year) was the BA square.  The 6933 and the 6920 that I bought in 2015 both had the Cerro keyhole

I just purchased a 6920 from Cabela's. It has the keyhole marking.  Any particular forging more desirable than another in a 6920?  I've owned several 6920s in the past 15 years.  I believe they all had the keyhole forging.

I've seen more keyhole (Cerro) marks and only some fewer square (Brass Aluminum Forging Ent).

My two older 6920 (2011 & 2012) both have the keyhole markings, also I have two 6920 lowers with the same keyhole marks behind the trigger.

From a practical standpoint, I do not know that one is better than the other. From a cloning standpoint, it does matter is you are trying to reproduce a period correct rifle.
