I had the same struggle in my 2013 Civic on washboard backroads with an iPhone 14 Pro in a MagSafe case. A basic magnetic vent clip kept sagging and blocked my AC and and a dash suction mount left a ring I hated. I wanted one-handed docking without sticking anything to the car.
What worked for me was the VICSEED 360. The hook lock vent clip bites onto the vent slat and hasn't budged on rough pavement, and the 360 swivel lets me park it on the outer edge of the vent so airflow still gets through. It snaps on and off one handed, no metal plate needed, and it's been solid with the MagSafe case and no residue anywhere.
Same experience here in an older Civic on corrugated roads, and I'm with you on your pick. The locking vent grip actually stays put, the swivel lets you park it at the edge so air still flows, and the magnets line up perfectly with a MagSafe case so no extra plate. One hand on and off is easy, and since it avoids suction or pads there is no residue left behind. It hits everything the original question asked for from rough road stability to keeping the vent useful.
