flagship or near-flagship with some requirements

I am looking for something akin to a Nexus 6 or Note 4, but I don't want physical or capacitive buttons and the Nexus 6 is just too oversized and can't be used properly face up on a desk. I don't have small hands, but I do want to be able to use it somewhat with one hand. I don't think I would like touchwiz, as I've used cyanogenmod or stock android on my last 2 phones. I am currently running lollipop on a nexus 4. What I like about Nexus 6 and note 4: beautiful large screens on both, front-facing speakers on Nexus 6, good camera. One thing I considered is putting stock lollipop on the Note 4, but then I still have the physical buttons and the stylus would be useless.

Price range: up to the cost of the Note 4.

Any recommendations?
