This is a great question. Obviously collecting or repelling balls anywhere on a course should not exactly be some question of formula, in my opinion. And obviously variety and subtlety has a whole lot to do with it. Variety, subtlety and particularly randomness in the sense of collecting or repelling a golf ball eventually gets into what one should assume to be a natural look---eg tying in the man-made lines with natural lines and formations so one has a hard time telling which is which. The best result of it done well for the effect it has on a golf ball once it gets on the ground should induce any player to have to study carefully all that's in front of him to try to determine what it means in this sense of repelling or collecting----eg how it might effect the golf ball when it gets to ground. Think of what they say in this way about TOC---most of which really is nature's own anyway. Is there any more to it really than randomness?
Once you've come to understand this in architecture probably the next thing to look for in the context of repelling or collecting of a golf ball is what one might refer to as "the margins for error". With architects like Dye, Muirhead, probably Raynor and MacDonald the "margins for error" are or are often noticeably thin--sometimes razor thin. With architects like Ross, Mackenzie, Flynn, Colt, Alison, C&C, Doak and some others today they are much less so.
While all of those above play great, in my opinion, in a collecting or repelling sense they do play different and they do look different. I like both because I like a broad spectrum difference and variety in golf architecture but there's no question in my mind that I like the latter style better because I think it just looks more like the real thing---the real thing generally being the look of nature's lines--and how they might repel or collect a golf ball once it comes to ground.
And in the context of this overall question I'll even give you an example of this collecting or repelling of a golf ball---perhaps the most amazingly odd and dramatic example of it I've ever seen. It was on the 13th hole at Royal County Down. On the tee I hit a good one iron although the hole was pretty long on the card. I hit that 1 iron because I just couldn't figure out what the tee shot was about and it looked like it necked in pretty good on the left that was formed by a beautiful diagonal natural dune ridge. So I got up there and had about 200 yards left to a back left pin. If I walked to the end of the ridge I could see the pin. I think there was a marker on the hill too around the center of the green. So my caddie told me to hit a 6 iron. Well, I hit a 6 iron around 170 at most which I reminded him off. He told me just to hit the 6 iron and hit it well to the right of the marker in the middle of the green. I told him the marker looked like it was about 10-15 yards right of the pin--and he said it was but just hit the ball well to the right of the marker (none of this I could see by the way). So I hit this 6 iron and I thought it was a helluva lot more than 'well to the right of the marker' and he said that it might be perfect! When I got around the ridge my ball was about two feet from the pin and I saw the enormous stretch of fairway cut approach well to the right of the hole that gradually inclined up into the dunes. My ball probably slung right to left about 50 yards.
Coolest damn thing I've ever experienced and I didn't even actually see it happen. That's why to me that hole (RCD's #13) is one of the neatest holes in the world. My ball collected from maybe 30 yards short and 50 yards right of the pin and cozied right next to it. And I realized if I hit that ball at that pin or even at that marker quite a bit to the right of it the ball very likely would've repelled off the green to the left.
To me that's an example of really great architecture in a collecting or repelling sense. It was the farthest thing from obvious---almost impossible to imagine really until it actually happened. I'm not saying all holes should be like that---but that one is a winner in a lot of ways including in a collecting and repelling sense!
