Having used a few rebuildables now I would definitely go with the dripper for ease and learning how to coil etc.
Certainly I wouldn't advise heading straight to a genesis style atty as a first go - they can be right buggers to set up when you're new at it and having the extra work of setting up the mesh and watching for shorts can put you off if you're not getting on well with it.
Run a dripper for a bit, the one from vapourhut.com are pretty highly regarded, and when you're happy you can get the coils right and know what to expect when you've got a coil ready then you can look to move on to a genesis or similar.
You certainly won't look back when you've been using a rebuildable though - nothing else seems to come close to your own set up
