I've always heard Naks are the best but let me relate an experience I had. While living in Champagne. Il. during the early 90s a Nak rep came to a local high end shop to promote his product. He offered a free test and tune up for any cassette users. I took my Teac V800X deck for the offer. The rep seemed truly shocked at the test results of my deck, and so was I. The spec sheet he printed out showed a flat and extended frequency response much better than expected. I have to say that in direct comparison it was difficult to tell the difference between source and tape.
I sold the deck a few years ago but it was still working great when it left me.
