Then hopefully the bad stuff about both will help you decide better:
HE500 cons: a little slow-sounding, bass is a little wooly, and overall like other Hifimans the fit and finish is not as good as Audezes
LCD2 cons: treble a little less smooth/grainfree, sound is much less open (many comment on it sounding almost like closed headphones, to which I share the sentiment), lacks dynamics
All relative to each-other, of course.
Sounds about right to me..
