Much of it depends on how one works, I think. I myself use templates, stock pictures, etc as they are available in abundance on the web, there is no real need to back them up. There are people who customize templates, stock pictures, combine them, etc. and store them in Documents and Pictures, where else?
I am not sure that restore in File History is faster than restore in Macrium Reflect, in either case you would have to lauch the app to do a restore. The difference is in the backup mode, FH working in the background vs MR backing up everything. They perform different functions in an overall backup/restore plan. I also begin to like robocopy, for that matter, another musical instrument in the band. I will be playing with all 3 of them this weekend.
