Why would you save a sheet as a template vs saving as a new sheet?

I have a master sheet that I plan to replicate multiple times retaining all configuration I have done ie workflows, attachments, predecessors. It appears that saving as a template and saving as a new sheet would retain all of those features. So what is the benefit of saving as a template vs saving as a new sheet (and vice versa), is there something obvious I am missing? Thx.
