Best way to do particles/laser beams?

So, I’ve been trying to learn the best way to do particles and laser beams in panda3d, I’ve found several options so far, there is the built in particle system in panda3d, there is meshdrawer which I can’t find any updated info on since 1.7 came out, and pyro, which I’ve been having trouble using too. So which is the best way?

thanks in advance.
