I'd mostly agree, but there are times that a tank with a decent factory coil is useful, such as while traveling and you just want to throw 1 or 2 blister pack coils in the bottom of your carry on than a rewicking setup. Yes, a kit can be small, and only take a few minutes, but if I'm traveling, the one thing I don't want to do when I get back to my hotel room is rewick a tank.
There are definitely situations where a standard clearomizer would be ideal. I have a handful laying around with a pile of coils for each of them just in case the need arises. I don't mind rewicking while traveling...it can be an inconvenience, but I got so used to it and rewick so quickly that I guess it's almost second nature now lol. I may get scoffed at, but pfft!
