I don't like to dip my nose to the string. So for me I wouldn't want a bow that had specs requiring that. BUT different overall cam sizes/design, the way the brace and ATA combine with that, and your release style/anchor point will make every bow a little different, even if ATA and brace are the same. Hoyt, for example has a cam design that increases string angle making a shorter ATA/brace bow feel longer. Mathews has HUGE cams, which might do the same (not really sure though).
As was stated you just gotta shoot them with your release, preferably with a peep/sight installed, to really know what is right for you. Specs alone will only get you an idea. Me at 28" and 70 lbs I much preferred the Ultra over the standard Helix, but I sold it (I also owned and sold a Realm X). I actually shot my Reign 7 better than either, although the Ultra felt absolutely great (my bad arrows were simply far worse than with my Reign 7). But I bought a Reckoning and am absolutely loving it at 35 ATA with smallish cams and a 7" brace. Best holding/shooting bow I've ever had bar none. I'd definitely put it on your list if you can deal with 325ish comfort (which I shoot) or 335ish performance (too stiff for me in a hunting situation).
