Anything wider than about 15mm is UltraWide on a crop camera. The 15-85 is close enough to UWA that I find I rarely use my 11-16 now.
I thought about selling it, but it is just too nice a lens, and I am sure I would miss it too much.
I'm just nob amateur , but i believe you are right . I have same impression about toki 11-16, got it for landscapes,some vacation pics, but i capture compressed images without focal range flexibility.
For example below, taken while driving towards Mount Robson,BC, was looking impressive from my point of view, but at 16mm, my max focal lenght, Tokina capture a lot of bushes left and right,lots of sky and ashphalt but the center subject,the highest peak in Canadian Rockies looks like a bump.
here is a crop from same photo, about 15% of the original dimensions, and this is what i could see with naked eyes;
