Restore from backup vs setup as new; big performance difference?

[JerTheGeek]

I have wondered about this for a while now. Is restoring from an iTunes backup that bad?
I have an iPad Air 1 that I just erased and then restored from backup to try and remove some of the lagginess of the PB. Anyway, I've used this backup since I first got an iPad way back in December of 2012. Sure, there is a lot of stuff I don't need on it but I really don't want to go through the hassle of redoing my entire iPad.
So, in general, iPhone or iPad (or iPod touch), is restoring from an iTunes backup a big deal when it comes to performance? Is it a good idea to start fresh every once in a while? I think we should be able to easily backup and restore to a new device without having to worry about the hassle of setting up as new....

Reset all settings usually fixes most issues. The times I've restored as new I can't say if noticed any significant difference between that and resetting all settings.

But there can be a difference between using an old backup and starting as new. But if you have issues I'd recommend the above instead cause starting as new is always a hassle.
