Some are really nice looking, some are pedestrian, that is true.
As for ease of use, I find that with some course guides it is very hard to read the distances to fairway bunkers, doglegs and other hazards from the tee, because the distances are only given from the tips. This means not only extra calculating, but also often the angles from the medal tees are just different so you are left guessing exact distances anyway. A sure way to keep people contemplating in stead of golfing and hold up play.
Also I like the guides which read like a flipover, that you can put in your pocket at the right page without damaging the booklet. So you don't need to look up the corresponding page of the next hole every time you take the booklet out of your pocket again.
The biggest objection I have to course guides is that they delay play, because everybody stands around looking at them for too long. At the very least it should therefore be easy to use and read. That is even more important to me than having nice pictures or drawings.
St George's Hill have a very good strokesaver, one that meets above criteria, and you probably have it. If not: It is printed by CourseGuide. Also I like the bandon course guides which the caddies use, but I couldn't get my caddie to sell me one.
