Then take TMax 100 and compare to any Ilford film and you'll see that your analysis is right out the window.
If you contact print 8x10 film, then grain should not be a concern no matter what film you use that's available in that format. You will NOT see grain. If you enlarge 4x5 film, Delta 100 is finer grained than FP4+. But not as fine grained as Fuji Acros or TMax 100.
