Scans do not say everything.
There are a reasons, why I put verbatim above most other brands.
Let me list them (again.)
1 Good quality (on all levels. Scanable and non scanable)
(ALso those Verbatim scan could be claimed better some of the others actually. So don’t go by scans alone.)
2 Good Availability (You don’t have to spend a afternoon for finding them) (I think all fail here, because they are old media.)
3 Good Customer Support (Sony and Philips come close of what you posted, but still are not the same level as Verbatim.)
4 Known reliable stability (Which removes the RITEKG04 disc from that list.)
5 Good Compatability
6 Good Priceing.
7 You know what you get. From the above Philips, Maxell, TDK have a reputation to switch MID’s and Manufacturers meaning it will be a suprise if it performs and works on your equipement.
Your scans are nice . Specially the RitekG04 ones, because most of them, that I personally encountered seem to be problematic over longer time.
But please keep in mind that verbatims solid reputation as safest available media was earned.
I said safest, because like you I do have some media which performs better as verbatim, but it’s poor available and/or expensive.
