I have been bow hunting since the early 90's and IMO, Scents are a waste of money, but it's not my money, so spend it if you wish, I just don't use them. I only use a grunt call if I see a buck a distance away, and I have killed a few that responded to the call,as far as rattling, I have never had any luck blind rattling, I have rattled a few in over the years, but never got a kill out of it, not saying it isn't effective I just don't think i am very good at it.
