Just from my own experience I'd recommend you go with an RBA, preferably the RSST and avoid the drippers for now. I started out with RBA's, and got good at rebuilding them, then got an IGO-W, which I found to be a real hassle to rebuild.
This is just my opinion, based on my own experience, and obviously the dripping fans will differ with me, but that's been my experience. I really don't care for my dripper, or having to drip more liquid into it all the time, or having to get the kanthal through those tiny little holes in the posts, or how the coils get gunked up with carbon so fast.
Conversely, if I need to re-coil one of my RBA's I just pull out the wick, wind some 28 kanthal around it, stick it back in, lock down the ends and fire it up. Hot spots are easy to work out with a dental pick, and it's a lot less hassle than messing around with my dripper. It will take it's place next to the Protank that's been gathering dust for months now.
