Yes, and do it from an iTunes backup, because iTunes does a complete backup, whereas the iCloud backup is somewhat limited. The limitations are listed in those Apple Support documents.
HOWEVER, do keep in mind that some people have run into problems that stemmed from either some settings they previously had or even an app that was causing trouble. SO, for troubleshooting purposes, I would personally prefer to restore as a factory default machine without any of my stuff on there (just yet) in order to see how it works absolutely clean. If everything is fine, then go back and restore from your backup. And if something pops up as a problem after it's restored, then you know it's not there from the factory default condition itself, but from something on the backup. This is simply a troubleshooting methodology, that's all.
Some people may not want to go through all those steps and simply restore it right then. If something is still a problem at that stage, you don't know whether it would have been there as a problem from the default setup, or from the backup file. To find out at that point, you have to go through the whole process again, and separate it out.
Anyway, I think you see the idea here ... :-) ...
