I have some Honda V6 engines I take of and I really like the Aisin timing belt kits, the brands of the parts in the kit are selected by Aisin and from different companies but all are very high-quality parts. I haven't used the Aisin kits for my Volvo but if they included a Gates timing belt I wouldn't be concerned about the quality, Gates parts are all of good quality from my experience.
I have read about counterfeit parts from Amazon and Ebay though, but I don't really know how much of a problem this is or if these types of parts somehow make it into the Aisin kits.
