Let me define it the way I am using it, both Dolby and dts have a codec, both are lossy, both have 5.1, only one is a standard, both will reconstruct the 5.1 speaker rig, but, one will take up 4x the room, so which one holds the same information using less space.

Ahh, so MP3, OGG, and WMA all sound the same also?

The main reason most of you say that dts is better is because that they have sweetening done the the high end (boosted bout 3dB) and the surrounds a loud on top of that (the full range of the surround channels boosted by 3dB), usually, when people say that they don't notice a difference, thats because it was encoded properly

DTS has never "sweetened" a mix. There were few cases back in the laserdisc days where DTS was sent cinema masters by the studios that were not attenuated and told it was a home master, and sent back to the studio an encoding of what they were sent. This resulted in some Laserdiscs having +3db in the surrounds and +10db in the LFE; this was the studios' errors, not DTS'. There has not been any DTS DVD released that has any attenuation errors or channel volume level errors (with the exception of Jurassic Park, which also had the same problems in the DD version, and a corrected DTS version was released). I can name several Dolby ones, though. DTS does not even do the encoding anymore. Please do not make up things. (this argument died back in 1997)

Just think about it, and ignore everything you have ever heard about AC3 and dts, they both do the same thing, they both throw away so information, one can do 5.1 at 448kbps and the other at 1538kbps, for example which do you use, Mpeg Audio 1 layer II or layer III, layer II has high bit-rates, but layer III will provide better compression when using M/S coding, which is how Dolby Digital works, dts codes all channel separately, correct? Dolby Digital will code the sound buy combining the common sounds (think L+R and L-R), abd then decode it ( [L+R]+[L-R]=L and [L+R]-[L-R]=R)

MP3, OGG, and WMA all sound different and do the same thing. Same with DD and DTS. Your logic is very flawed.

@Ruined
dts's cinema codec is better because if will provide a better sound than any of the codec mentioned in this thread, it uses only ADPCM compression, which uses the differences between samples to compresses sound, by far one of the best compressors if used properly. Scalability has nothing to do with a codec being better.

DTS Home uses sub-band ADPCM coding just like DTS cinema's codec that you are touting and all five main channels are full-range, unlike DTS Cinema which does not have full-range surround channels. DTS Home does not support some of the features that DTS Cinema does, such as triggered events and data cues to move on to the next CD, however these are features that would not be useful for the home environment and are more suited for the cinema environment.
