I was just giving the poster some attention when I said "aluminum is best". It's best for me because it's light and I don't do tricks. I like the fact it doesn't rust, too.
Yes, steel is slightly heavier, and aluminum can possess the same strength, it's also less reliable, and breaks instead of bending. The OP is looking for a strong, cromoly framed BMX to do some basic tricks and stuff. It's perfect for the op's needs. There is no "best". I have bikes with aluminum and chromo steel frames. I've had my aluminum frame have a crack, and I was forced to dispose of it. The OP is just looking for confirmation that their choice is a good one.
