Get the Black Cats, they're better. Brand does matter, trust me. I lit both those brands side by side not too long ago, the cats won.
However, if they have them, Texas Outlaws are the best. They may be called something different where you are, but they'll be in a red or yellow box with individual crackers inside. Those are among the best these days. I remember when Cherry Bombs and Silver Salutes could still be bought... man, I miss those... blow the crap out of anything. But thanks to some stupid kids who blew their arms off, they're illegal now. Pipe bombs are still possible though I don't recommend it unless your experienced. Me, I've actually made factory fireworks, so I understand the process well.
Get sparklers too. Lot's of them. The ones with the wooden sticks, not the metal ones, they suck. You can tie them together tightly(leave one in the middle sticking up so you can light it safely) and when you light one, they all erupt into a giant fireball.
Headbombs are freaking amazing if you can find those.
I'll stop being a pyro now...
