It depends, if you are not pushing your subs anywhere to their limits then a few dB more by inverting anything may not amount to anything and in that case you should pick the one that produces a smoothing response. Also, unless you can listen to music without moving your position at all, i.e. frozen in place. Otherwise you should also check the response within your listening "bubble". With bass, even a few inches away from the MMP in any direction could make a few dB difference here and there.
All auto REQ software, whether by Dirac Live, Audyssey, Anthem, Trinnov requires you to use multiple mic positions, typically at least 12 to 18 inches from one to the next positions, to the right, left, upper right, lower right, front and back etc. for that and other reasons. Good looking FR curves is only good if it also sounds good to you in the end. That's another reason I gave up using my minidsp, because even if it makes your FR curve look flatter, I don't believe it will make things sound better over all, than using a good auto REQ system like Audyssey and Dirac. If what you have now, do sound better to you overall, then for sure stick with it, but in my experience, it really is not always easy to tell which ones sounds better with movie contents.
