Firstly all of the miniDSP 'plugin' features work in parallel with Dirac Live, which included the crossover filters you asked about but also crucially the time delays too. This is critical for subwoofer integration as the optimal setup comes from setting these two manually first, and then running Dirac Live on the resulting main speakers plus subwoofer(s) combination.
For context I went from applying REW filters on a 2x4 HD to using Dirac Live on an SHD. One key difference is that Dirac Live is set up to be based on using measured data at multiple measurement locations and targeting a form of average, whereas most people just generate REW filters at a single location (I did). It is possible to use multiple measurement locations in REW, take an average (ideally weighted to the MLP) and then generate filters for this but it is easier to do so in Dirac Live. This for me is probably the single biggest difference which I do thing gives better results. Overall DL is probably more accessible and easier to use for most the REW too. (Although personally as I'm familiar with REW there are some aspects of DL I don't like in comparison.)
The other significant technical difference between DL and filters in REW or Roon is the improvements DL filters bring to the impulse response (time-domain performance). It's easy to confirm with measurements that improvements are made but I still think it's open for debate how audible such improvements may be (others here will know more to comment). It's impossible to only apply the phase corrections in DL but not the amplitude changes and so not really possible to try to test to assess this.
Thanx for the detailed answer, now i need to decide if the difference between shd and flex make me upgrade. I am not in usa so i pay more to get it here. Here is the home of the Three Pyramids of Giza.
