I ranked DLBC>XT32>ARCG based on:
a) effectiveness of FR and impulse response improvements, not based on subjective impressions in listening, but on graphs posted on AVSF (very few as you know, hard to find such few from over a thousand pages of posts) and ASR (quite a few by not just me, searchable easily).
b) manual adjustability.
On adjustability, if you read forum posts on AVSF, you might get the impression that they are great, best blabla but without details.
Here's an example:
You can see that the interface looks beautiful, in this sense I would reverse the ranking to ARC Genesis > XT32 ($200 app) = DLBC
If you look at the adjustability, that matters most, you can see the following limitations of this interface:
1) Room gain can be adjusted between 0 to 6, but if you grip the handle and move it between 0 and 6, the curve would move, but you cannot change the curve shape to the way you want it, you can stop it at the point it looks closer to what you want but that's it.
2) Deep bass Boost (dB) can be adjusted between 0 to 6, but same restriction as in 1), useful but a lot less useful than Audy and DL obviously.
3) For 1), you can vary the center frequency between 150 and 300 Hz, that would work not too bad if they allow multiple points of adjustments, but no, only 1 is allowed.
4) For 2), you can vary the center frequency between 20 and 80 Hz, same comments in 1) applies here.
5 ) Above is the so called system-wide target, so if you have 4 subs, or even 2, you will not be happy, well, unless you one of the AVSF fans on that huge Anthem thread.
6) For the front, and surround channels, when you make an adjustment, it will apply to the pairs only, no individually, vs Audy and DL's that let you do it on per channel basis.
Now, let's say your post calibration results show that there is major bump at around 55 Hz, Audy, DL, even YPAO/REW would let you level that off easily, yet with ARC G, there is no simple way of doing it. You can try lowering the room gain, and/or deep bass settings and try different center frequency, you may be able to lower the bump by a couple dB but it could/would make/create another trouble spot.
That's my major frustration, that Anthem would not improve on manual adjustability, never mind the nice looking graphics, but focus on allowing adjustments similar to Audy app (preferred), Dirac and REW's (PEQ/BIQUAD). For clarity though, while I managed to get excellent results with the $20 app, I had to use it with Radbudyssey (freeware) and it could a lengthy process similar to trying to make improvements with ARCG's beautiful interface.

So those keen on the benefits of RC, should budget $200 as minimum to include Audy's $200 app (they do offer discounts such as 25% iirc..) sometimes, or $700-$1000 to include The DL license. So Anthem wins on this as all models come with ARC G and the excellent mic kit.
Anthem ARC G clearly has potential and I don't believe it would take them much to improve it to the point that it could match Audyssey+app in terms of effectiveness, but I understand for a relatively small company, they might not want to risk investing their resources on something when the vast majority of their customers seem happy enough, many even think ARC G is already the best, much better than Audy and DL. That's great for them, but it does leave some of us (I know I am not the only one), seeing that they have great potential but might not get developed further in terms user adjustability and effectiveness.
D+M owners also has another trump card option, that many users like the fact that it is an automated process, using REW to do the RC/EQ part and yielded great result quickly, that's thanks to
@OCA 's freeware:
I asked if he would do the same for Anthem AVR/AVM owners but he said he had done a script that decodes the ARCG file but could not do more as he's not going to buy a device to continue the work on that, sadly..
