As typical, we tend to agree a lot in general, but just to be fair in this case, people (not you as I know you have used both and are not the hearsay goer type) can say anything based on their subjective measurements. On objective measurements, I found that if you just run the two following instructions, SubEQ and DLBC would make little difference overall. If you do the same, but REW them after, tweak accordingly, then REW again, tweak again, then yes DLBC will win quickly (again just overall).
For someone who would do the same but in full OCD mode, after a few hours of REW/tweak and cover multiple mic positions, very similar results would be achievable with either system, but DLBC will take less time for sure. That's purely based on my own experience, experimenting on two channel stereo, with 1 or 2 subs. For those with 4 subs, I don't doubt DLBC will win even bigger.
