^Soft keys are a reason NOT to get the MAXX HD. Using screen space for buttons is incredibly stupid. All the ROMS and MODS for the DNA (to which there are many) have button remap options, such as long press and such for alternate actions.
I just switched from the MAXX HD to the DNA. I switched because I really HATE the crappy AMOLED screen in the GS3/MAXX HD. I can literally scale out an entire desktop version of a web page on the DNA and see every single letter, no matter how small it is.
I also switched because the MAXX HD had become almost unusably laggy. I amost noticed MORE lag on the MAXX HD on my OG MAXX.
I'm a bit bummed that the DNA does not have a micro SD slot, but in reality, the audio quality of the sound coming out of the headphone jack on almost all Android phones is pretty horrible. Very few use Wolfson DAC's, so the audio quality is pretty crappy.
I do not like the battery life of the DNA. If I can figure out the awful lag. I might switch back. But the screen is incredibly beautiful.
MAXX HD / Galaxy S3 have the same crappy screen:

I might switch back if I can smooth out the issues I'm having with my MAXX HD.
