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.
