Reception: great as long as your area is solid - much improved with the OTAs it's received. 4g/3g handoff is excellent now.
Camera: improved, but still lackluster. If you have excellent lighting, and no movement, it can take excellent pictures. But any movement (by you or picture), or anything less than solid lighting, and it takes some work to get a decent photo. Low light with the flash look washed out often. It's not bad, but definitely not the best.
Screen: this is extremely subjective, and there are a lot of threads here already comparing screens. The Bionic has the most practical screen - easy to see outdoors, easier on the battery than the others (same as DX2 and D3). It's very bright and I find it to be a relief to look at after some of the other new devices. However, due to its inherent nature, sometimes you might see a "screen door" effect (very subtle, but sometimes noticeable). I will say, the Gnex is a much more beautiful screen, but dimmer and a bit more of a strain in the eyes - IMHO. This has been debated endlessly, and you really need to just look and compare yourself, as its all very subjective.
Battery life: I'm adding this as I feel its important. The Bionic battery life is significantly better than the Gnex, and marginally better than the Razr.
