Cartos tend to "mute" the flavours a bit, atomizers tend to give a "cleaner" hit.
tanks are fill'n'forget until they empty, bottom-feeders require a squeeze/sqonk every once in a while to reload the atty.
Some people prefer the way a box handles, some people prefer the feel of a tube.
Bottom feeders have a bit of a learning curve, tanks not so much.
You can change the
juice in a bottom-feeder 'instantly,' tanks, not so much.
Both have advantages, both have disadvantages--but there is no reason to rule either out, you really just have to decide which to try first
