Well higher alcohol beer for one. I have used some sugar in the past and I have had to let it bottle condition longer. I know form wine making that the higher the alcohol the greater the "bite" there is. In beer there might be some off flavors that are undesirable. In time it might taste good, but it is going to take a couple of months. As far as the buzz factor it will do the job.
I am sure others with some more experience will provide more information.
