They aren't in the same league in terms of size and motherboard real estate, either! The NH-U9S has pretty much the same footprint as the stock Intel and AMD coolers and won't typically block memory slots, etc. at 125 mm tall, it will fit typical mini-tower cases.
In between the smallest and largest Noctua tower coolers you cite are several versions of 120mm and 140mm fan towers that might make sense if you have the room for something bigger than the U9S.
The U9S, the U12S, and the U14S are all pretty much the same design, in small, medium, and large sizes. All three can be run with one fan or two fans. Unless you need extreme cooling in a massive case, those are the three Noctua models I'd be looking at, with size in the case being a prime consideration.
I'm trying to buy an NH-U9S for a mini-tower case as soon as they are available.
