I would recommend having a mixture of both if possible. The thing with cfls, is they don't have the best penetration, so you want to have them as close as possible(without burning them, of course) to benefit most from them. I try to surround the plant in as many places as possible, and when you flower you will want to get to each bud site with lighting.
Side note: I would recommend looking into canopy management, and low stress training, as these will help you to better convenience yourself when growing with the cfls.
Thats just my 2 cents...But what does a doctor know? Jk
