There were some somewhat lower quality batches of T02 a couple of months ago. They seem to have shown up more in the Fuji T02s, but later batches seem to be fine. To be safe I'd go with the Sonys since they're more recent. There's always a chance the Fujis could have been on the shelf for a while and be from the "bad" batch. I say "bad" because they really weren't bad discs, just not as good as TY usually is.
