Well, I Googled Graf's BP AFTER I posted my question. I did find a very good post on a forum by someone who did an informal comparison. This is what I found:

My order arrived and I got a chance to do some testing of the Graf powder. The first thing I did was to compare the volume vs. weight of Swiss, Goex, and Elephant against the Graf powder. I used a 100gr volume measure for all the measurements.
Graf 2F= 102.6 avg.
Swiss 2F= 106.6 avg
Elephant 2F= 104.4 avg
Graf 3F= 98.7 avg
Goex 3F= 97.8 avg
Next I went out a shot some of it to see how it performed against other powders. All of the testing was done with a Ruger 77/50, RWS caps, Harvester crush 50/45 sabots and a Lee 300gr FN cast bullet was used. During testing the only variable was the powder charge.
Graf 2F 120gr= 1455fps ES48 SD18
Elephant 2F 120gr= 1438fps ES37 SD21
Swiss 2F 120gr= 1724fps ES13 SD6
Swiss 2F 100gr= 1591fps ES13 SD4
Pyro RS 100gr= 1495fps ES29 SD14
I also tried the Graf 3F against Goex 3F, but testing was very limited. Using Goex 3F with 100gr volume gave a velocity of 1487fps. The same load using Graf 3F gave 1400fps.

If anyone here has experience with it as well, I'd sure like to hear that as well!
Thanks!
