I have had no issues hitching up with the truck at up to a 15-20 degree angle from the trailer as well as when the truck is slightly off level compared to the trailer. The worst that it requires is maybe jacking the tongue up a little higher than normal to get the bars hooked up. Sometimes when the truck and trailer aren't level to each other one bar will need a bit more elevation to hook up. No issues.
My hitch has also been very quiet. Maybe it's not rusted in yet as I only have about 3,000 miles on it, but no don't get any squeeling, screeching, etc. Just the occasional pop or creak when making tighter turns in campgrounds or something. Nothing I can hear unless my windows are down and certainly none on the highway or normal roads.
I think the hitch works pretty well. I've never had a sway event, but wind does blow my rig around a bit more than I'd prefer sometimes. It blows the rig as one unit and it always stays in line, but would like a bit more solid feeling. I think that's mostly down to our trucks' weak suspensions and marshmallow p-metric tires though.
