the reese one is just a sleeve that slides in, and nothing to hold it in place so putting in a big hitch is not fun when the sleeve slides back as you are putting in the hitch. the GM one fits the receiver and has a lip on the front so it does not move and the holes line up. the one I had fit very tight so no extra movement, I had to use a rubber mallet and some wd40 to get it out.
That "lip" is VERY important, reinforces the sleeve where there is a lot of stress, I wouldn't want to use a sleeve without that lip for heavy towing. If I had a large TT I'd upgrade my insert/head, but that's just me.
