I donâ€™t think that is still an issue. The specs for both + and - are available to everyone who is willing to pay, I donâ€™t think they are holding back some information that only benefits consortium members.
Nec is using + since the ND 1000A, so they have about 8 models experience since then.
Technically there is no reason why a NEC canâ€™t perform like a benq with the + format and, in fact, I think the Nec is still better with some + media.
I only use + media and have some brands I prefer to burn with the NEC and some I prefer to burn with the Benq.
Itâ€™s the same thing as with the â€˜legendaryâ€™ Nec 3500, it was a great burner then, and still is a good burner now, but it isnâ€™t the best anymore. Not only specswise but also in writing quality. Many people are copying each other opinions, and apparently, get stuck in the thought that the 3500 still is the best burner.
Yes it was great but now there are others that perform at least equal and sometimes better. I have compared the 3500 and the 3540 with at least 6 different media types (scanning with the benq1640) and Iâ€™ll choose the 3540 over the 3500 almost any time.
