Overall I prefer the look of the DLX over the HA as the robot doesn't look as "gangly" and I don't like the look of the arms, hands, legs or feet on the HA. Also I suspect that the DLX has a more screen-accurate colour scheme with the lesser amount of blues, gold/yellow, blacks throughout -- I don't know, but then again, putting screen-likeness bias aside, I can see how those colours on the HA help to break up the blandness of the grey and accentuates/compliments the look of the toy.
Something that bugs me about the DLX figure - and I'm curious to know if the HA has this or not
(apologies if you've already mentioned it, it's about 07:20 here atm and I'm being distracted by my daughter who's exploring our Tokyo hotel room and letting everyone know about it
) - but DLX Soundwave suffers the same problem with his hands as with DLX TF Prime Cliffjumper... i.e. NO wrist articulation! This in itself wouldn't be so bad if the hands or forearms were positioned so that the top of the thumbs were aligned with the inside of the elbows, thus allowing him to bend his arms and say point a gun at someone or something. But now, because the thumbs are aligned outwardly sideways to the inner elbows, it means that whenever he bends his elbows it's like he's doing arm curls (or shaking his fist at you or trying to give you the finger if he had the articulation for it)... either way, lame. Didn't like this on TF Prime Cliffjumper, sure don't like it on DLX DotM Soundwave... I sure hope HA Soundwave doesn't share this flaw.
