That depends on what you're looking for. The Slams tend to offer a more controlled ride due to their stiffer sidewalls. They also balloon out less (which could help with whatever caused your last bag to fail), and lift higher.
However, the Firestone bag drops about 1/4" lower than the Slam, so you may lose drop if you switch...
Firestones also tend to be a few bucks cheaper, depending on where you shop.
My choice is Slam bags all the way, but again I'd recommend replacing them in pairs!
