Rima is the best of the best. I am not sure what you are asking, but don't worry about your scans. I have gotten better, but when your numbers are as good as this it really doesn't matter. One thing you will want to do is keep your scans at the same speed (8X for BenQ) when you want to compare.
Unfortunately, if you don't want to shop online, you will pay more for your media and you will get lower quality. Fuji TY has had problems, which is a shame considering the markup. If I were to only buy in stores I think I would stick with Verbatim.
Also, keep in mind your TY is 16X. As good as it is, the best scans I see are on TY G01 or G02 burned at 4X.
