Like so many have already said, its individual preference and nothing else.
Personly I swere by my e-pipe. Just a simple 601c. No fancy bells and whistles. 3.7 volts and standard size cartoz.
But then again... I am waiting for some deliveries during this mounth (variable voltidge and I-clear 30:s coming my way) so in another couple of weeks my preference.might have changed.
Whatever gets you through the day without analogs is good. Whatever setup you look forward to vaping simply because you like vaping it, is even better.
Keep on vaping and good night.
