As far as I am concerned, and this is strictly my opinion, there is no "best," absent some very specific and unusual criteria being specified.
All of the major backup and restore utilities, whether in their paid or free versions, seem to do just that very well.
Tech geeks seem to love Macrium Reflect, even in its free version, because it has so many switches you can flip as far as customizing it is a twiddlers paradise. It also does its job very, very well. It does not, in my opinion, have the most user friendly interface for "your average user." The UI definitely matters in some cases, and it needs to be considered.
I have used AOMEI and Macrium in the past, and both are just fine for doing what they need to do. I finally settled on EaseUS not because it's better or best at its core function, but because the others I wanted to have using it independently to kick off on-demand backups when those are needed have the easiest time with its "For Dummies" style UI (and I hasten to add that this is not, in any way, meant as a criticism of EaseUS or the user - simpler is very often better, and under the circumstances I have prevailing it definitely is).
