Again, it depends what need you're trying to fulfill. I'd take a bubbler any day, just because even the little bit of water it holds makes the hit so much smoother.

However, if space is a consideration, a spoon is always handy.

Finally, if I ever take weed with me somewhere where I couldn't easily conceal a bubbler, I just take a pack of zigzags, and it's all good.

To be honest, if you have a nice bong, I wouldn't get either and just get papers and a better bong!
