Golden Sabre has their hyped "driving band" promotion, but then all JHP ammo is basically shaped like that, so it's kinda unimportant.
Actually, in my own tests, the band is functional in two ways. One, average velocity was
slightly higher (reduced friction bearing surface). The second and far more important benefit was that the reduced diameter forward of the band and before the ogive allows more taper of the case mouth, which enhanced feeding reliability in a couple of my guns that had been finicky.
From my own tests in clay, I found both the GD and GS to perform well, with the GS usually penetrating a little deeper and it's jacket remaining in-tact more often than the GD. Because of these differences, and because of the benefit in feeding reliability, I chose the Golden Sabre for my defensive handgun loads in .380, 9mm, .40, 10mm, .45 and .38/.357. As an added bonus, the GS is a little less expensive than GD.
ETA:
I can't find the image of my Gold Dot test, but this was the Golden Sabre in .380 (102 gr.), handloaded to 1067 FPS (from my Beretta 84 FS). The clay was shot using my P3AT, so I imagine the velocity was maybe 40 or 50 FPS lower (never chronographed them from the P3). One layer of denim was placed over the block. The bullet fully penetrated the 12" block, but bounced off of the phone book behind it.
The bullet was in-tact when recovered, but the core and jacket separated while I was washing the clay off
This .380 load actually made a larger cavity and out-penetrated a 115 gr. JHP 9mm Remington factory load fired from my PF9. With no exit hole, it was difficult to cross-section the block cleanly, but you can see the bullet at ~ 10" of penetration.
Both of these test loads were fired from a distance of 15 feet.
