Seriously, if you know of some good, unbiased Gnome 3 reviews, please post them here. Thus far, I've never read a single one.
You can't have good unbiased reviews at the moment. Gnome3 hasn't been released yet, and all you can try at the moment are buggy LiveCDs. You have to wait until Gnome3 is released and can be installed in a real life distro and used over a period of time to do some real work.
I have tried Gnome3 on several occasion both under OpenSuse and Fedora after downloading test ISOs form http://www.gnome3.org./ Things that annoy me most are: huge while blurred glow around all windows, very limited configurabilty, having to use the mouse too much, very buggy system.
Things that I liked are as follows: in few places there's cleaner and more simple GUI, new notifications.
I will give Gnome3 a chance some after final release when I can test it in real life situations. At the moment I can't tell for sure if I will like new Gnome and I'm a bit worried that eventually I might have to look for another desktop environment.
GNOME has stagnated, and is of little value these days. KDE is offers more features, better performance, greater reliability, and just an overall better experience in every way.
What is the point in relentless chase for more features? I am pleased with spartan Gnome, and to me it offers better experience. People have different tastes, and beauty of Linux is that you can choose different desktop without being forced to use something you don't like. In my opinion it would be better if more energy was spent on adding features and polishing various applications instead of desktop environments.
