Just the opposite of OtheroneK: I've heard quite a few NT2000 recordings that I like, like the build on Rode's in general, have never owned them but I do have a pair of 414 XLS's that I love to pieces. Definitely a case of, "You'll get my 414's when you pry them from my cold, dead fingers, etc, etc..." Back in my studio days I used B-ULS a lot, they would get beat to hell and still sound great. Build quality on the XLS's is just as good and I don't feel I have to really baby them.
My feelings for them aside, I will say this: I find that my 414's can sometimes be a little finicky in some venues when it comes to placement and pattern configuration. I've had a few pulls in small clubs come out muddy and I've had pulls in medium sized spaces (3000-5000 ppl) that were beautifully balanced and audio gold, in both settings thinking I was adjusting to the room's strengths and having good mixes. Probably still getting to "know" the mics capabilities. There are plenty of samples at the LMA, but if you're interested I can point you to some of my recordings. Good luck!
