Gold Dots are generally better, but the Golden Sabers are not bad at all. The latter tends to expand faster.
The thing about Gold Dots is that they give very consistent performance across a wide range of conditions. They do not expand as much as some others like Golden Sabers, but they also rarely fail and work just fine through clothing, car doors, and just about anything else you can throw at them.
Since we do not get to choose the conditions under which a cartridge is used when things get ugly, I prefer reliable terminal performance under broad conditions over slightly better terminal performance in narrow conditions.
I've used everything under the sun, and honestly I do not think it makes that much difference in an unobstructed shot, which most are. I tend to go with Gold Dots because of their reliability through weird materials, their relative inexpensiveness, and because the bullet design is a good match for my cartridge preference (165gr .40).
