AntiNewtonRing glass brings the disadvantage of 4 additional surfaces to collect dust. In my experience, focus never was a problem. I wrote some documents just for me about different workflows. What can I say: After a while it gets boring and I discovered better or faster way to do my scans.
For instance, I first did a RAW scan of 1 GB of the whole scan area. Afterwards I loaded those scans into VueScan and that software did the clipping more or less automatically. Even better: instead of moving the scan rail to each negative exposure, I had one go and could adjust tone scale afterwards. That was a lot faster. And a lot less annoying noise, too.
So far I didn't discover bugs on the Merills after updating the firmware. They do have flaws, of course, but optics and sensor are hard to beat in their size class.
