I prepared the following table in order to highlight differences and similarities. Bold characters signify an improvement for what I conceive to be typical radio amateur use.

The UV-B6 is not covered here since the only difference from the UV-B5 is a flashlight instead of the rotary encoder and alarm button of the B5.
My main sources are the blogs of PD0AC (UV-82, UV-B5/B6) and the Miklor FAQs
In general I think the design of much radio equipment is lagging behind other electronics when it comes to user interfaces. Imagine a smart phone user interface on a handheld! That is why I emphasize user interface issues in my final evaluation.
I like the improved front-end, signal meter, and squelch of the UV-B5 making it a strong contender for the winner position. But I don't think they are worth the price of a poorer display. On the other hand, the UV-82 is inferior in my view to the UV-5R due to the need to enter the menu for VFO/MR and band switch functions. So for now I'll stick with the UV-5R.
