In the book “The Variable Contrast Printing Manual” by Steve Anchell
there are several interesting charts which shows the various ranges of
paper/filter/grade for an Omega D5XL enlarger and developed with Zone VI
Developer. Are there similar charts using other enlargers/developers? Or
a comparison of Zone VI developer and other developers?

There probably are, but you really should do them yourself. For example,
for years I used Zone VI developer 1+2 at roughly 68*. Fred Picker of
Zone VI recommended a 1+3 dilution for 2 minutes. Well, I had problems
with contrast, and I checked tons of stuff, filters, light leaks..., but I
could only get a true grade 3.5 Finally, I used the "develop for 6 times
the image emergence time" advice. Boom. Grade 4.5. So for years I
wasn't getting the contrast that I could even though I was following the
manufacturer's advice. In my system, I needed to develop for significantly
longer. So, get a Stouffer 4x5 31-step wedge. You can contract print it if
you don't have 4x5 enlarger. While using a reflection densitometer can
take the guess work out of analyzing it, you can do a very good job
eyeballing the the prints. How many distinct steps can you see between
black and white in normal print viewing light?
BTW, I have a perfectly good Macbeth reflection densitometer that I'd sell
for $100 plus shipping, but as I just said, they really are a luxury not a
necessity.
