Based on the numbers is seems like the Pure Wings 2 is better, lower noise and higher airflow/pressure.
I know this has been asked before but I'm hoping for a concise answer.

Would replacing the NF-A9x14 PWM with a Pure Wings 2 on my NH-L9a improve performance?
If nobody has tried specifically with the L9a I'll just buy a PW2 and test it out.

it should work fine, but the pure wings 2 is a 25mm fan while the noctua one is 15mm

Yea, I have the height support in the case I'm working with now... I think.
I did just bite the bullet and ordered a Black Ridge off OC.co.uk so I also have that to test with when it comes in.

With 10mm extra depth, I would expect the bq to be able to scoop and push (static pressure) much more air than the Noctua. It should do much better.

Static pressure is not the limiting factor with such a small heatsink.

The stock fan is excellently paired to work with it. You would not get better performance switching to a different fan.

The pressure and overall airflow are higher, so mathmatically I should see better temps. I know Noctua designs are pretty specific so the L9a might be designed to work best with their specific A9-14, fins/pipes etc.

Still looking for a SW2 but I'll be posting all kinds of temp results when I get my pure all assembled.

How did this turn out?
