I'd tend to side with the guy that has 650+ more courses played.
I played Wilderness last July and I think it's a 4.0. I didn't even think about it as a course in consideration for any type of "top courses I've played" list, which is basically all the ones I would give a 5.0 or 4.5. It's a pretty bland place. No cons really. Just no overwhelming pros either. Quality baskets, tee signs, and tee pads. Mostly all good holes but none that I recall really being a "signature" type. I'm not being negative. 4.0 is "excellent". I need a lot more special "feel" or some more really memorable holes for me to go above that.
