Since you're looking at full towers, that should be Antec 1200. I would do either the HAF or Antec as well.
Another reason I was gonna go w/ the xaser is the Remove able mobo tray.
Personally I like the look of the top one (since I know my liking it matters a lot to you ). Nice cases, I think you are in the great situation where any choice would be a good one. Enjoy whichever you choose.
Yeah, an Antec 1200 is simply massive. I don't see how it could be considered small by any means. Also, it has extremely good airflow.
I just got the CM HAF, it is a fantastic case. It looks good and it moves a ton of air w/o a great deal of noise. Also, quite spacious.
