TrueHD or DTS-HD MA when Star Wars (& other Lucasfilm movies) comes to Blu-ray? Both?

When I put in a DTS HD-MA disk I find the ideal level to be -10 to -5.( -5 being louder on my receiver than -15) If anything the DTS HD-MA codec is forcing less volume into the mix than Dolby TrueHD.

I do however, notice slightly better separation in the speakers and a miniscule improvement on dialog and surrounds when using DTS HD-MA over Dolby TrueHD.

To make any truly meaningful comparison/contrast between the two, wouldn't you have to use a title with both TrueHD and DTS MA tracks? Are there any titles that offer a choice between the two?
