A lot of people, when about to buy a new piece of equipment for their interest, get confused about which one to buy. Although, neither of them would be a bad choice, but both of them would have some advantages over the other and will become a preference for a certain type of people. So if you are someone who is completely new to this game of the kush then you might want to consider going for a bubbler instead of a bong.
In the beginning, when you want to start smoking, you might easily get influenced by a bong. You want to keep your hits low and steady and be able to enjoy it at the same time. There is no point building up a developed need after a first few times so you might want to take it slow, with a bubbler.
If you are someone who is on the road all the time, then I would also suggest you to buy a bubbler instead of a bong. Bubblers are smaller, more compact, and are made easy to handle so that you can take them anywhere with you and not be away from hitting a few breaths of the good stuff.
Although both of them can be close to the same price as each other, some places sell bubblers cheaper than bongs. So if you are on a budget or are a college student who is not looking to spend too much on this, then you can go try out the bubblers for smoking.
I would say that going for a bubbler basically is a great choice as it serves the same purpose in a relatively easier way.
