Well I'm completely new to this so forgive my ignorance. I have looked at all the information on these units and also on the sponsor website. I was questioning wheather one unit is better than the other and if this is overkill for a small setup.

I wouldn't say the -R is overkill at all on a 12" cube, by any stretch. I have one on mine and it's just right I think for a low-light, non-CO2 setup. I get very little algae but still noticeable, if slow, growth.
For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.
