I used the NH-D14 for a long while on 1366 and 2011, mounting is a breeze and you get a good mount every time in my experience. The cooler also performs amazingly well, but we all know this from benchmarks.
Looking at the Phantec, it looks like a straight copy of the NH-D14 with some tweaks and I'm sure it performs really well as well.
Myself I would still go Noctua because when people say their products are quality and well made, it's not like when you generally hear that and it's just brand preference speaking, these guys really make quality stuff. Everything is made in Austria, they also have a solid history making excellent fans, of which you get two of with the NH-D14.
Customer support is also excellent. I lost some mounting hardware and emailed them, the next day they sent me replacements. When I moved to a 2011 mobo, same story, day after my email they sent me a 2011 mounting set. The only drawback is it comes by regular post from Austria and takes about 10 days to arrive.
My vote goes to the NH-D14. Also if this is still the case it's another bonus; when I bought my NH-D14 it came with a large 10g tube of NT-H1 paste - one of the past TIMs out there.
