To me the AMG line looks better. The question is, what options will be there for 2022? The AMG line at the moment (2021) does not come with the AMG steering wheel. The basic steering wheel looks boring to me while the AMG looks like a piece of art. Very subjective of course.

Early Daimler press releases indicated that the AMG Ride Control used a predictive system to adjust the active sway bars. The releases seem to imply cameras are involved. Several of us on the forum have tried to discover what actually drives the active bars on the ARC. Or what the ARC is really doing.
Trying to judge from the "feel" of the ARC, it seems to soften bumps better than E-ABC, and do it only on the side needed. The E-ABC seems to see the road ahead (sometimes) but adjusts (relaxes) both sides equally. Comparative result - E-ABC is good on speed bumps and railroad crossings, but not potholes affecting one side. ARC adjusts for that pothole, but I don't know how.
The ride is certainly better with ARC than standard AMG53 Air, and I wish I knew the mechanism.
Audi and Porsche use active sway bars, options that cost about the same as the AMG Dynamic Plus Package on the 53. Are they different?

The AMG system does not use cameras. In fact compared to the electronic suspension it is kind of a throwback since it just a rollbar stiffener (aka decoupler) basically the same optional system as the previous GLS550 and standard in the old 63. I hope its evolved since the old one was not very good, basically it went from jittery to floaty with nothing in between.
However there is little similarity to the ones you mentioned, and it has evolved. Different tech.
The ARC uses step-motor controlled Active Sway Bars, exerting a leveling force, not just re-engaging decoupled sway bars.
What I don't know is how the car decides to apply its swaybar forces. It seems to sense a high frequency suspension action, and permit that travel (like a pothole), but resists a slower acting movement, such as a cornering force, lean, lateral acceleration, rotation, or what?
It behaves much differently than the previous generation AMG63, which I thought was unacceptable. "Jittery" was kind - I thought it was more like "Dentist," and didn't stick on rough surfaces.
I like the ARC.

I'm convinced now that you're right, there are no cameras involved with the ARC, AMG Active Ride Control.

The comfort of the AMG C mode is comparable to the GLE air suspension in S Mode…where I set mine. The C mode GLE is Boaty, IMO and rebound damping insufficient in any roller bump like a traffic Berm…it bottoms out with a thud.
As far as performance, I would like to see 0-30 numbers…I’m guessing the GLE 53 would outperform the the GLE 580 to 30. It feels like V8 torque but as some have said you don’t hear much exhaust sound inside unless the windows are down. Like many other cars, there is a slight lag downshifting after coasting at lower speeds. The engine turbo boost spools up instantly (with the electric compressor) but the TCU hesitates as it shifts down multiple gears.

"The S 65 Coupé's exclusive AMG ACTIVE RIDE CONTROL suspension prepares for bumps in the carriageway ahead before the vehicle drives over them. To do so, AMG ACTIVE RIDE CONTROL combines active suspension springing with continuously adjustable damping. The system precisely scans the condition of the road ahead with the help of a stereo camera to optimally adjust the damping of each individual wheel to the upcoming bumps ahead of time."
