Yeah, I've never seen Campbell's, so I'm only going on hearsay.
Portsmouth is actually really good, and I'm not one to be real into the RTJ thing. It does encourage gripping and ripping, which can be fun, and there are a few ocean/bay holes.
As for Renaissance, it's still on my list of courses to see. The head pro there is a former Myopia assistant, and I got to know him a bit while at Myopia b/c he used to give lessons there before the RC range was ready. A fellow Tedesco member of mine was the original club developer/president, but has since left amidst all of the struggles the project has had. Despite the long wait, I hear the course is actually pretty good. There are apparently many waste areas and classical throwback touches on the course. I will have to check it out one of these years.
