I have seen no definitive answers to your question since there has been no scientific research completed that I am aware of on this subject.
I have used just vinegar, just sugar and now I am starting to use just glucose. I have not tried the booze yet. In my situation the vinegar and the sugar work well as long as you don't overdose them. As far as negative effects from these two carbon sources, I saw none.
The theory is that perhaps different carbon sources drive different bacteria. This is hard to prove unless done under scientifically controlled circumstances. As far as hobbyist's responses, IMHO most systems have too many variables to make competent decisions, especially if the bacteria are not properly identified. Most hobbyists do not have the ability to properly ID bacterial types.
As far as the effects of the different carbon sources being used, there is some scientific documentation regarding high levels of glucose, sugar and a few others. Too much of these carbon sources can cause detrimental effects for coral. So overdosing is not recommended.
