+1 on The Kracken. This and Captain Morgan's Black are very similar, but Kracken is priced cheaper. The bottle is really cool, too. They are both blackstrap rums, so they have the characteristics of the rich vanilla spice, dark color, and higher alcohol content than regular spiced rums.
Sailor Jerry's is OK for regular spiced rum, but for the same alcohol content I'd rather use a blackstrap rum to get more complex flavor.
