I personally had the atrix and loved the fingerprint reader and larger screen, but I could not stand the plasticky feel of the device and the retina display did look a bit better.
I honestly the feel of the Atrix doesn't bother me at all. Sure it doesn't feel as solid as my iPhone 4 did, but I don't feel like I'm holding a piece of junk either. Another plus is that I can have 48 gigs of memory with the 16 internal and 32GB micro sd card. Of course the next iphone will probably hold 64GB, but we are talking right now. I have not had a chance to theme my phone so I can't compare it to a jailbroken iPhone yet.
