This is probably super relevant, I'm surprised this hasn't been posted yet, the guy seems to get a lot of praise. Here is an awesome review.
My personal opinion is, I already have a Gnex and LOVE it, so I have no need to upgrade. Also, I'm one of the people that really don't like that home button. I rom a lot also, so the insane dev support on the Gnex is awesome, and will always been there since its a Nexus, making it simple and on the front line constantly.
