I have not done a direct comparison, because in my setup, I have found very little audible difference between Audyssey, and A1 Evo Acoustica when using flat target curves.
got Acoustica dialed in with the last version
A1 Evo Acoustica is a fantastic tool and if you can follow the instructions, is simple enough to use without technically understanding what it does.
Try A1 Evo Acoustica first. It’s free and made an improvement to me over stock Audyssey.
I used to eq everything myself but switched over to A1 Evo Acoustica recently and love it. It really makes it slap.

AI summary — not a quote
Dirac ART (Active Room Treatment) is widely regarded by enthusiasts as a significant advancement in room correction technology, moving beyond static EQ to actively manage modal energy decay. Users report that it effectively eliminates persistent room nulls—particularly in the 25–70 Hz range—resulting in tighter, more uniform bass and improved dialogue clarity. While praised for its ability to 'wake up' speaker systems and provide a cleaner, more immersive experience than previous iterations like DLBC or Audyssey, it is noted for having a steep learning curve and requiring manual fine-tuning to achieve optimal results.
Pros
- Effectively eliminates significant room nulls that other correction tools often miss.
- Provides tighter, more tactile, and uniform bass across multiple seating positions.
- Improves dialogue clarity and immersion, especially during heavy low-frequency effects (LFE).
- Successfully integrates diverse speaker types, such as mixing sealed and ported subwoofers.
Cons
- Steep learning curve; described as not 'idiot proof' and lacking adequate official tutorials.
- Potential risk of speaker damage if supporting speakers are configured incorrectly.
- Default target curves are frequently criticized, necessitating manual adjustment or custom curve loading.
- Limited hardware support, currently restricted to specific high-end AVR models.

Dirac ART is an amazing product imo - but buying it as a $900 firmware upgrade to one receiver that they won't even transfer for you when your receiver dies under warranty is pretty close to a scam in my book.
ART results are excellent but... the price is too high, customer support is almost non-existent, license is tied to one avr, the interface needs work and the interface is buggy. Add to that the program itself is not intuitive- it's not at all a one-click solution.
ART sounds amazing and I love it. But, is it worth $800? I’d say no.
ART is definitely worth it if you have subs spread around the room or surrounds that reach low enough.
There are other reasons to complain about ART besides not being able to transfer the license. It's buggy, the interface could be greatly improved and the company's customer support is basically social media. ... The default results were awful in my system. Now that I know how to adjust things... oohlala it sounds amazing.
