Though I do not agree about SMOK I will say that building your own coils is cool but that gets old too. I started off building coils and wicking years ago and then got tired of having to do it so went back to premade coils with
tanks like the super tank, prince, beast, Falcon etc...
I have several RDA's and RTA's and I'm not going to lie to you; a good tank such as the crown, Falcon etc will provide just as much flavor as RDA or RTA. In fact these newer
tanks with premade coil/wick units are so good that they sometimes taste better than anything I can get out of a rebuildable. Just something to think on.
I prefer the convenience of drop in coils over building now.
