The bigger it is the bulkier it will be (harder to move around and might get accidentally get knocked over) and harder to clean. Consider how hard it will be to get a pipe cleaner in its hard to reach spots or how much cleaner solution or regular water you need to appropriately fill it. I personally have gone with smaller and smaller bongs over the years due to these factors. If you want a cooler smoke invest in a dry herb vape with a bong adapter. A small bong with a simple perc and ice catcher will get you smoke as cool as a person really needs. I would pay no more than 100$ for a bong. The fancier it is and more parts/glass it is the harder to move and maintain, that’s my 2 cents.
