a buddy of mine who has both says that the only con of a side load is that you cant maneuver the dabber as good on the nail but they still get the job done.
I currently have a top but I want a side because of the fact that some oil is left on the dabber but with a side load I could place it more on the nail and spin it...If you get what im saying lol
I think with side you can catch more of the smoke that escapes. Smokes travels up so thats the only thing i could think of. Besides what Soxfantony said up there sounds like the 2 factors
