I typically take 2 shots of any subject to experiment with various development times. I was satisfied with my initial D76 1:1 @ 20c/68f for 6 minutes, so I neglected the 2nd negative until I decided to try Thornton’s 2 Bath HD developer just to see how it would handle the same exposure.

Now, these are scans and not matched the best in curve placement, but good enough to see the differences between the developers.

In the 2 bath, I gave baths A&B equal time at 4:30 @ 20c/68f with a water stop and TF5 fix for 4 minutes.

Since I print with a condenser enlarger, the Thornton’s neg might be easier to print closer to grade 2 than the D76 negative, which in my experience, must be printed at 1 or 1.5; maybe even lower than that.

Wonder how the negative in D76 would print split grade. Somewhat surprised that Thorton's did not separate the clouds more, , was under the impression that it was highly compensating. Nice shot though.
 
I do see a slight difference when I switch back and forth between the two. I see it in the contrast of the belfry shutters and the shadows under the shrubs, but both pictures are very, very close for sure.
