I'm Team Canister.
I always take a canister. It's easier to hide, but not easier to pack. We've ultralighted and used a garcia can for a weeks worth of food. We did have to use a little ingenuity

, but it all fit. I've even taken two for a really long, not-so-ultralight trek to accommodate a week and a half of food. It comes in handy more as a table than a seat, especially because we have some big agnes pack chairs. And it's a good place to put contained garbage rather than some random spot in the pack.
Bear Country.
The Uintas might be different but it is still bear country, may be black bear country, but nonetheless, bear country. That means a clean camp. A bear follows their nose, not the dirtiest camp even though @
Udink makes a good point and I've heard of the dirty camps getting the "best" bears. Still, a clean camp is the best way. The times I've been in the Uintas I've never found a tree that was, 10' off the ground and 8' out from the trunk. Isn't that what it should be?
Different areas have different bears. Alaska is in a class all its own. Montana and Yellowstone are Griz/Black bear area. Further south it's just Black bear. See Griz country below.
Easier.
Yosemite requires canisters for a few reasons. They're
fool proof...you can be as drunk as you want

. It prevents tree damage from over use. And the bears in the central sierras recognize tree hangs and can get them down. I've had my canister kicked around a few times and I've been glad each time.
Treeline.
Treeline doesn't matter. Bears will go wherever they smell, or have previously found, food. The bulk of the John Muir Trail is above treeline where a canister is truly the only option. Watch the mountains episode of Planet Earth and they showcase Griz hunting moths well above treeline.
Griz Country.
Glacier and Yellowstone have specific camps set up to do bear hangs. There is is regulated as such. The food hangs and kitchens are designated a certain distance from the tent sites to protect all people. Only in these areas have I found it useful to use the hangs, mainly because they have built food hangs to a specific height and width to keep bears away. There they also recommend, if not require, that the clothes you EAT in you leave with the food to prevent bears from sniffing around a clean camp. More and more Griz move further south into the Winds every year. We should treat all the winds as Griz country and if a hang isn't adequate, use a canister.
Practice safe whatever you choose and read up on the local requirements/regulations. I'll have to post a TR of my first trip to Yosemite and our endeavors to "see" bears. Let's just say I'm glad my friend had insurance

! I'm team canister, the bigger the better.
Nice topic @
Nick, I always enjoy a good discussion.
