The Droid DNA looks like an awesome phone but the lack of SD card would keep me from getting it. As for me, where Android's concerned, RAM is king and I wouldn't consider any model that didn't have 2 gigs (that and the 2 gig models have FAST processors to go with it).
The Droid DNA, Galaxy S3 and Galaxy Note 2 are the current spec standouts. Since the Droid DNA only has 11+ gigs true available storage, that leaves the Samsung models shining IMO.
Good luck with your choice. It's not an easy one.
