I would push you towards the RL and skip the BL, but get yourself a powder funnel set-up too.
Dillon stuff is a baseline against which all other brands of turret and progressive consumer grade stuff is measured, so you won't be making a mistake. That is not to say this is perfect, but you will be getting what you pay for.
If you don't mind handling the primers, then there is nothing wrong with the BL version. If you ever think you will want to use a drop for anything else, or if you want to avoid handling individual primers, then you get the RL version and still use an external powder dispenser with a funnel and use the automatic drop for other things down the road.
