A 107 is unlikely to be well tuned for 16x media codes, as it's not a 16x drive - you may even find that it drops them to lower than 8x, so I wouldn't consider 16x media at all.
The 8x Verbatims are probably a better bet than the 16x.
The dye code on the media detemines the write staretegy gor the drive - eg. if it says TYG02, it will treat it as TYG02, even if it's fake.
Among the non-faked codes, there are good and bad examples, like the G04 / G05 codes that are now insanely variable - a good example can be really good, but some can be awful.
As well as the name on the media (which you DO know), the media code (which many online suppliers do give), there's the country of manufacture, and the actual maker (made for "X", by "Y") is very common, and also the grade .. Grade A, grade B etc. are widely thrown around, but it's hard to determine.
The other toughie, what media does the drive favour... that can make bad media look good, and good media look bad.
