AT&T is set to release new 4G LTE phones on March 18, but is it better to buy the Nokia Lumia 900 when it comes out or wait for the Samsung Galaxy S3?

Rumors are swirling about the Lumia 900 release being pushed back until mid-April, but AT&T has a banner up on its website heralding an exciting new addition. For Xbox 360 fans and Microsoft Office users, the Lumia 900 is the best way to take your documents and games with you. That's especially true if you live in one of AT&T's LTE cities. Those super-fast up- and download speeds mean better gaming and faster document transfers.

Samsung hasn't given a release date or price yet for the Galaxy S3, only saying it will be out in the first half of 2012. But if it comes to AT&T, it's certainly likely to run on the 4G network. Furthermore, because of the power and success of the Galaxy S2, the S3 should be an amazing phone.

It comes down to what kinds of things you like to do with your phone, and despite how powerful these two will be, there are some important differeces. As mentioned above, the Lumia 900 runs on the Microsoft system, so the software will look somewhat familiar for many people. The Galaxy S3, however, should be powered by the Android 4.0 system and have futuristic features not found anywhere else.

Start the slideshow to see how these two superphones stack up. Tell us in the comments what features you're looking forward to the most.
