OK, I would be glad to jump in here:
1. I don't hate Sense, so to me, this is not an advantage for disadvantage. A tie for your average user.
2. The Camera is better on the Rezound. Advantage Rezound.
3. ICS isn't without its faults. Newer does not always mean better. Rezound will get ICS AND a good Gingerbread ROM is nothing to sneeze at. A virtual tie.
4. Screen resolutions are the same, but there is an edge given to the Nexus in overall quality. There are some instances though, where the Rezound looks better.
5. Nexus is lighter. Advantage Nexus.
This is just my opinion.
You can disagree on any one of the points mentioned above, add new things to your list of considerations and score things the way YOU want. For example, the better camera may not be a consideration for you, for me...it is a big consideration.
In my group of friends, the same points listed above has given the group impression that these phones are similar enough that there isn't a BAD choice, just a right choice for YOU.
What I won't do is try to tell anyone that my opinions are fact, or that you need to substitute my opinions for your own. I am lucky enough to have used both devices and formed my own opinion.
