Never heard of the "quicksilver" myself but like Deadeye said I assume you are takling about the silver surfer.
While I own a surfer, alot of my friends including my roommate have the Q tower.
They are a little different the way they operate, the Q tower is cool because its alot more hands free with the fan and bag and even when using the whip.
I personally like my surfer because it is a little better suited to vapetubing (using vaporizer thru your bong) and it enables me to get much larger rips through the tube because of a more focused larger controllable heat pull, I am not a fan of using whips.
If you are not interested in vape-bonging, I would suggest the Q Tower for sure. (You can vape bong with a q tower, the hits juts are not as large as I need)
