I tried individual bottle priming with my most recent adventure. A cider. I will say that priming each bottle, even with carbonation drops (or Domino Dots) sucks. It is so much easier to prepare a priming solution, add it to the bottling bucket while siphoning the brew into it.
I also do not like the idea of using a bucket with a spigot for fermentation. IMO the spigot is a great place for harboring contaminates.
Another thing is what I don't really like buckets for fermentation. My choice, if money was no object would be a stainless steel conical. But, since that is way out of my budget, I like Better Bottles. They are clear like a carboy so you can see what is happening, but you are not in much danger of severed arteries or tendons like you are if you use glass carboys.
