Well, technically it's not a bag, but for home storage, and great for transportation, I use the Pelican iM2100. Case fits nicely in the safe. Always in an environmentally / climate controlled area. Perfect size for MY gear. Will survive Zombie Apocalypse, etc...
 

I have the 16mm and it's probably my favorite lens out of the four primes I own. Excellent image quality and absolutely perfect for low-light situations where you want to tell the story and maintain a lot of context, namely at wedding receptions or high-energy events. 
 
But, I would love to have the 10-24mm because I love shooting landscapes, get paid to shoot quite a bit of interior, architectural stuff and HATE having to change lenses when I'm either out in a windy, dusty environment or on the clock and feeling the pressure. The limitations of the 10-24mm that occur to me are 1) it being f/4, giving it a disadvantage for handheld low-light work 2) no weather sealing, keeping me on my toes if I'm out shooting landscapes in if-y weather.
 
But when considering how I intend to use it, I can imagine it being very useful. I shoot interior/architectural work on a tripod no matter what lens I'm using. I don't like using lights for interiors because my clients hire me for the natural look of my work, and no matter the lens, I'll shoot f/5.6-11 to keep things in focus. So the f/4 aperture isn't really an issue for either shooting situation. The lack of weather sealing wouldn't be a huge deal either. If the weather is inclement enough to potentially brick my non-weather sealed equipment, then I'm not going to enjoy being out there either, so things go back in the waterproof bag and I jet. 
 
I'm planning to buy the 10-24mm, as well as keep the 16mm. They both do different things really well.
 
TL;DR Consider the type of shooting you do and if the benefits outweigh the cost. 

If you need the low-light and almost-macro-like capabilities, then get the 16, or else the 10-24 will be a more versatile option.
 
I couldn't get both because $$$, and I wanted a lens which could be used for street, landscape as well well as astrophotography. I ended up getting the 16. I almost exclusively use it at 1.4 or 2.0 and couldn't be happier with the results.
 
Both are phenomenal lenses and you can't go wrong with either.

Ordered 7/7/16. Was to ship 9/8/16, but I changed credit cards and payment did not go through on the 8th. Sorted everything out this morning 9/9. This afternoon, I checked my account on B&H and I've got a UPS tracking number. I should get it by the 14th - It's on the way.
