GTs, NF-F12s and FD Venturi HP-12s are all about equal in my books. By far the three best options. NB-eLoops would be included but you can pretty much only run them in push. Apart from that they're great. EK Vardars aren't bad but can't really compete with the ones mentioned before. Really don't know why anyone would go for Corsair SP120s, unless they really want that look or can't afford better. A word of warning though; FD Venturis have a very slight motor tick to them. It's very quiet most of time - practically inaudible - but some times you get unlucky like I recently did. I'm currently in the RMA process with 2 Venturis with horrible ticking that's audible to 5+ meters, we'll see how Fractal handles it. IME Noctuas have no audible ticking at all.
Personally I've been going with FD Venturis lately simply because PWM Industrial Noctuas have been kind of difficult to get for a while now and I needed black fans. If you can deal with the looks, go for the NF-F12s, unless you need the 2000rpm industrials. In addition to the quiet operation and great performance, Noctua has by far the best warranty and RMA system in the business, which is a big reason why I've used them for my personal systems and client builds for a LONG time now. I have Noctuas that are 5 to nearly 10 years old running in many builds no problem, and the few fans I've had to RMA have been very swiftly replaced every single time.
