Eric, Yamaha uses Parametric EQ filters. ...And very few of them, and not low enough (around 32Hz).
Audyssey uses FIR EQ filters. ...And a multitude of them, and down to 2Hz (or it could be 10Hz; one or the other, still very low anyway).
ARC (and other systems) uses FIR and IIR EQ filters. ...And there are various flavors, just like with Audyssey.
There is a lot to read about them, and I cannot explain briefly here; you'll have to do your own research.
And then, after all you can read and learn, the next step is to experiment! Wow, it would be real nice if all of us we can do that, and do it properly too, but we are restricted, the most majority of us.
So, what to do? ...Read Music In The Round's column in Stereophile by Kal Rubinson. ...That's a start; then try few of them for yourself, among the best ones, and be happy all along the way and until you reach the ultimate absolution of your own Room Acoustic Treatments: RAT. ---> That is my own patent btw.
By your explanation Audyssey is the better program. Don't worry about research, it's my middle name. Anything that $100 or more that I want or need to buy, I research until I'm literally sick and believe me, it is voluminous. When I went to buy my current car (and all the ones before that) my research spawned a folder 4 inches thick! The folder on my Nexus tablet was 1.25 inches thick. The folder on my Roku was almost 1 inch thick, the folder on my current Onkyo was 3 inches thick and so on. I can not afford to experiment. I do not have the income to even be in this hobby so it's more risk than it is hobby for me. Why would I want to read a shil publication? I never read audio magazines (or any magazines). They are just mostly ads for crap one doesn't need and shills for the manufacture of the week. All I can do is try to find truthful sources such as ones that explain how things work, that's a really good thing to know because it acts like a filter. Google is great for that.
