I also have the 3x for my Ioniq 5.

Steering is about 25% better than HDA when solely based on lined lanes, but the 3X is able to adapt to situations that the LKA/HDA would just disengage (such as passing through an intersection) or a random car parked on the side of the road.

I routinely use it even on NYC streets and grass parking lots. It's about 80% accurate in avoiding unexpected cars and larger obstacles or following simply a "laid down" grass trail from a previous car in a grass lot or field.

I did buy it expecting results like in the "Taco bell" video -- and was disappointed under those expectations at first, but after a reality check I still decided to keep it and have easily driven 40,000 miles with it since.
