First three or four albums. Just smokin stuff. He had Pearly setup like a "Man's guitar", until BB talked him into going light.In fairness, when Billy was playing his best stuff he was using 11s.
Eddie is another famous user of 9s.
What was his best stuff? I always like Tres Hombre myself. Have you Heard and Beer Drinkers and Jesus ...... For me, by far his best stuff. The top 40 stuff was ok Sunglasses was a killer groove. Some of the other top 40 stuff? Ehh
9-gauge strings suck. No tone. No feel. These are highlighted when using a thick plectrum.
On my G&L Jerry Cantrell Rampage ( 25.5 ), the springs on the Kahler Pro Series 2320 tremolo are only geared for either 9-42 or 10-46,...it came with 10-46 on it but to use heavier guages, I'd need to change the springs to Kahler bass tremolo springs.
I use 9-42 on my 25.5" G&Ls, and use 10-46 on my Gibson 335s and Pauls...except...
...my LP 1960 Classics came with the Gibson Les Paul Signature Strings in....9-46. After experimenting with various set-ups with 9-42 and 10-46, I finally settled on going back to the 9-46. I also found these to work really well on my two LP Supremes. That's what works best on those four guitars. But I have to be very careful to not over-bend on those treble strings. I may try to go back to the 10-46 sets, if only because keeping track of string inventory is a PITA.
Some guitars can be very finicky about their set-up and string gauges. Be sure though, to check the radius of strings at the saddle. It should match the radius of your fingerboard. You may need to file the saddle notches on the Tune-O-Matic bridge. No matter what string gauge you use, doing this will have your Gibson playing "like buttah".

I am just making the point that some may prefer this or that, but to make a statement that tone sux with certain strings? Imho, the pick thickness, angle of attack, force of attack are far more important for tone. Unless you are playing in drop FFF with strings flopping around so much that buzz cant be avoided.
I just can't feel comfortable playing with anything less than 11-52, even on 25,5" scaled-instruments.
And I DO bend strings, mind you.
Now guitars in standard tuning sound tinny to me frequently.
