The Reese is a little quieter but more picky about being adjusted well. Round vs. trunion doesn't matter expect they are limited somewhat with respect to ratings, like round only for 1000, trunion for higher.
It's really getting picky between the two. Both have many happy owners. Pick the cheaper one? I love my Reese. I have hated it at times as well when it was not adjusted correctly. Scary at 60mph, rock solid at 75mph is a matter of getting those cams centered.
You should get some real weights as to properly choose the right strength. TW tends to creep up on RVers.
