No experience with Nanuk cases, but I'd go with Storm over Pelican as I find the latches easier (and quieter) to open than Peli's 'knucklebusters'. FWIW, since you mention weight, the Storm im2500 is lighter than the Nanuk 935 (which is in turn lighter than the Pelican 1510).
One more point to consider is that while the Storm and Nanuk padlock holes are just case plastic/resin, the Pelican holes are reinforced with metal, so arguably the Peli is a bit more secure. I'm not too fussed about that, since I figure if someone is going to go at the case with a hacksaw they probably have plenty of time anyway.
Thank you, Neuro. As always, you're very helpful. I've read several threads on CR and other forums about Pelican vs. Storm. Many people, including you, mentioned that Storm cases have better latches than Pelican ones. However, it seems that Pelican changes the design of its latches a few years ago and now they're much better than they used to be. But Storm cases are lighter, and this is a big advantage. I think Storm cases are a little more spacious inside as compared to the corresponding Pelican cases. Pelican offers a lifetime warranty, but I’m not sure about Storm (do you know by any chance?).
However, the more I read about all the cases, the more I got confused. Some people mentioned that their Storm cases leaked and could also bent if you put something heavy on them. Not sure if it actually affects the gear inside the case, though. I've read that some Pelican cases could open, thus exposing all the stuff (but I've already got SearchAlert Extended Hasp TSA Case Lock, which you recommended in one of the threads).
It may all be very rare cases, though. But I just want to get the best case that I'll be using for many years. Same as a tripod/monopod
I wish I could figured out myself which case to buy, but unfortunately my limited knowledge doesn't allow me to do that.
Here's of the Youtube videos about the Nanuk cases.
