New set of tires

I purchased a set of 225/60/16 Michelin MXV4 Energy Plus V-rated tires for my 06 Impala LS. And I was wondering if I should have went with some Michelin X Radial tires instead. And being that both set of tires were just 45 dollars each I decided to get the Energy tires. But I was just wondering if I should stay with the Energy's or sell them and get the X Radials. Thanks for the help.
