Best Portrayal of the Alien

I also dont think the Xeno from Aliens was mindless they was acting as far as a purpose within its Hive Colony and they actually showed a lot of intelligence and out thinking the Humans on LV 426 on more than one occation.

I do prefer the look of the Original Aliens head however, and so yes a modern look based on the Smooth Head is the one i favor.

The protomorph in covenant and AVP aliens in my opinion 

The revelation of xenomorph learning and strategy in Aliens was a boon the the whole AVPverse.  If there were some cut of the xenomorph in Alien 3 that kept the scenes in the director's cut but retained the canine origins, that would be great but we can't have nice things I guess.  I almost hate Resurrection but I did like the design and movement of the xenomorphs that weren't white baby face.  How they sacrificed one of their own to escape was one of the best things about that turd of a movie.  
AVP 1 and 2 on PC was great playing as xenomorph, so was playing as "6" of AVP2010 for PC.  In AVP 1 you really had to think and strategize like a xeno, destroying lights and being sneaky and patient, waiting for the right moment to show a poor fool what nightmare fuel looks like.  I miss playing that online and hiding up in a dark corner and lmao as dumb human players backed right into my jaws.  Also the one time I was in a match with lifecycle mode on and my xeno team kicked so much marine butt, (especially myself, one marine player said I was God) we all became pratorians and the marines left the match.  We were like...sooo what we do now?  We need marines.  I was like, "I'll be your huckleberry...", left, rejoined, and beat them undefeated until they all quit.  Good times.
