Of course we'd recommend the NS!

Seriously, though, I'd say try each one out. Best Buy generally has a demo unit (you may have to ask them to see it). The raw hardware specs are probably going to be better on the Atrix and Inspire, so if that matters to you you'll want to by-pass the NS. I'm of the belief that unless you're gaming or doing CAD drawings or something intensive on your phone, the real word performance between the NS, Atrix, and Inspire aren't going to be
that big. With that said, the NS seems to perform quite well on games. Need for Speed runs quite smoothly. But some people want the bigger specs and benchmark numbers.
So why'd I choose the NS? For the main one, see the first bullet below. The other big reason is that the NS is like building your own PC. The only thing on there is just what I want on there. I don't use Facebook, so guess what? No Facebook app! The other reasons can be summed up as: It's a really nice phone, and performs quite well. [Despite what the NS haters would have you believe.]
- The Nexus phones' software comes directly from Google. Your phone will always have the latest version (bugs and all!). [This doesn't mean you get it instantly, just that you'll be running the newest before anyone else]. Rarely can the same be said for carrier/manufacturer phones.
- The Nexus phones are easily rooted and are easy to switch ROMs on. (Though this isn't something I do).
- The Nexus phones are developer phones, so theoretically, there should be a higher degree of app compatibility. (Since you would assume the devs use the Nexus as the baseline for their app.)
- The carrier/manufacture phones generally have more features (like the Atrix!) and sometimes the addon software is very useful
- The carrier/manufacture phones *may* have fewer little bugs in them. I personally have not had any issues with my NS, and those I've noticed are just minor. Others have had more serious issues.
Just be sure to look closely at the NS specsheet to be sure you're OK with it. (No SD slot to add more memory is a big one folks get hung up on). Hope this helps some
