Anyone who says the Sigma is 'quite soft' isn't using the lens properly. The lens is sufficiently sharp, even @500mm, if you stop it down properly and use the necessary technique. I use it on a D90 and D300s, and it delivers images sharp enough for stunning 8x10 prints. Unless you have clients that want ultimate image sharpness in 20x30 inch prints, the Sigma is an excellent bargain. Sure, if you have money to burn or you have top-shelf clients demanding the ultimate in image quality, buy the primes. Otherwise, give up on trying to impress people, and go out there with the Sigma(or the Nikkor), and enjoy yourself.
If you go by the groupthink here, the Sigma is a piece of trash that will guarantee you low acceptance rates. The answer: forget about acceptance, and get to work creating your personal aviation vision.

Either will be fine, although the 80-400 AF-S should be superior optically. If you check the database, you'll find great pics from both. Me, I've given up on zooms and have gone to primes for the image quality. I got spoiled the day I bought the 50mm. I just can't go back to zooms.

I shoot with a D7100 and it is in my opinion the finest camera to use for all but studio photography. The crop sensor gives you a 1.5 multiplier on focal length. The AF is amazing and the metering is very accurate. Coupled with the large sensor you have the best of full frame and crop sensor cameras at a very good price point.
If you look at the sales literature it is a semi pro camera. Yes, this camera amplifies every flaw in every lens you put on it.
In determining what lens to put with it, I have tried many. For aviation I use a Nikon 70-200 2.8. When I shoot small aircraft I couple it to a 1.7 Teleconverter. To me it is all about the image, with this lens the colors are brilliant, focus so sharp it will amaze and the percent of keepers will be over 90%. The added benefit of this choice you can control the amount of foreground clarity allowing you to make aviation compositions instead of airplane pictures. Lastly it will allow you to advance your skills from an armature to a pro level photographer.
For me what started as a hobby has evolved into a profession, due to my skills and equipment. Think about what you are investing in.

Properly used, I have seen results from all three lenses (Sigma 150-500 and both versions of the 80-400) be quite acceptable.
I have never used the Sigma 150-500 so cannot comment on how good it is to use.
I have both versions of the 80-400 Nikon. While the new version is noticeably sharper, faster focusing, and better VR than the first version, it is also heavier and larger. The old 80-400 fit easily in my lowepro camera/laptop backpack, the new lens on my D3s or D4 is a very tight squeeze.
