Was looking into getting the Radiant Max

Hi AT&T 

   Originally I was looking into getting the Radiant Max cause I saw it got a lot of positive reviews on your site and Walmart.com etc. But some people on here recommended that I dont get it due to its Predecessor Radiant Core not being a good phone. What drew me to this phone was the Battery Life, Storage space, Screen size, and Price tag. What makes this phone more unique over the Radiant Core other then the Storage, Battery, camera, and size? What has improved?
