Yeah, it boils down to whether it runs fast enough for your application. Static memory allocation is going to be somewhat quicker, but I just CAN'T see the justification, personally. Especially given the HIGHLY variable nature of the beast, in that one minute you might have no particles, the next you might have explosions galore in the middle of a blinding snowstorm. Moreover, it's more difficult to dynamically assign more space to one system with static arrays and maintain the consecutiveness. In fact, in terms of dynamically assigning space, I'm guessing linked lists are going to be faster in most cases, since if you want to maintain consecutive layout, it's time to screw with where everything else is.
But the statement "linked lists are too slow" is just hands-down ridiculous. Are they slower than static? Yes. Are they too slow? Absolutely not. Again, my particle system and many others that are based on linked lists run perfectly fine.
