This war would affect me exactly 0.0%. But since I've always been biased towards DTS, I root for DTS:X.
I'm curious, outside of offering higher bitrates and discrete 6.1 on DVD why are you a DTS fan? While both DTS HD MA and TrueHD are lossless, TrueHD offers better compression and other things like Dialnorm and Dynamic Range Compression, whereas DTS does not.
After some goofing around with atmos and DTS x demos, I have to say I think atmos is a lot better. DTS claims to be adaptable to any speaker layout, you just configure your speakers the way you like and the processor figures out how to create the sound, atmos does the same thing, but isn't quite as flexible as DTS x, at least on paper. DTS x also claims to be compatible with the typical atmos layouts, but I've discovered this isn't the case.
Playing back the DTS x object emulator using a 5.1.2 configuration with top middle height speakers, the only time the sound from the floating ball hit the heights is when it passed overhead between the fronts and surrounds. Floating overhead towards the front or back of the sound stage, the sound was collapsed into the bed channels. The same effect happens with neural x, height effects only work when the sound is between the surrounds and fronts. With atmos, height from the front or the back is phantomed between the front speakers and top middle or rear speakers and top middle. DTS x seems to work a lot better if the height channels are configured as either front height or rear height vs top height channels. Dolby's surround upmixer is also 1000x better and more accurate. I've watched several non atmos movies using both neural x and Dolby surround and I honestly have a hard time distinguishing an actual atmos track from Dolby surround. I've also set my bluray player to output 2 channel PCM on a couple occasions just to see how well it managed to figure out what should be routed to the surrounds and again, it's nearly as accurate as the 5.1 mix, much less of a crap shoot than Pro Logic II. with neural x I've heard sounds hit the height speakers that shouldn't be there, like cars driving by, Dolby surround seems to correctly route sounds to the proper channels 95% of the time, and unlike PLII, there is no channel bleed. Music just sounds plain awful with neural x, which is surprising since neo:6 worked much better with music than the old PLII. I have such a strong preference for Dolby surround that I always set my bluray player to convert DTS to Dolby Digital when playing standard DTS tracks, since my receiver can't apply Dolby surround to DTS sources for some reason.
