Restoring iPhone 5 as new, or from backup?

[parkm13]

I have had an iPhone 5 from about a week after launch. When I got it, I restored from a backup from my 4s. That backup has been used for about a year. The past few days my new phone has been freezing up for about 5 seconds randomly. Everything from opening messages, to unlocking the screen. I have tried turing it on and off, all that stuff. So now it comes to a restore, will it be better to restore as new, or won't it matter? Thanks in advance for the help!
