I chose a Zilog single-source part several years ago on the basis of it doing the job better than anything else in the price range and cheaper than anything else available. After my subsequent experiences with out of spec processor problems which occurred several times when batches changed, and Zilog's response to those problems, I would never again design with Zilog processors if it could be reasonably avoided. I'm not suggesting that their average product is bad or that my problems were typical of what you can expect with other of their products. Just that the experience was so bad and so expensive that I'll try to avoid it ever happening again. The processor I used was the Z8plus Z8PE003. Problems related to bad startup under certain conditions which affected some batches of processors and not others. Most worked as per spec sheet. Others didn't. The problem was trivially easily reproducible "on the bench" without using my circuitry but Zilog never managed to convince themselves to believe me. The problem quite probably related to internal reset issues, and on a processor with no external reset pin that gets "important".
