I have both right now... PAN and BOB...
I have ordered about 8 different Breit-style CALF models from BOB recently...
OUT OF THE BOX: The BOB is actually a better strap in looks as the Panatime is better to wear... AGAIN, out of the box...
The panatime seemed to be softer and formed easily and quickly but also seemed to carry PAM strap attributes...
HOWEVER, the reason the BOB takes a little more time to break in is because, it actually has a thicker bump made into the strap like the GEN does...
it actually makes the strap look more substantial...
I prefer the BOB based on it physical attributes...
Hope this helps...
