Well from a 5b, 6a, hJC, j.B, j.C, j.D, JC, j.C, j.D, 623+D, 236+C, 214+C rather than a 5b, 6a, JC/HJC, j.C j.D, JC, j.C, j.D, 623+D, 236+C, 214+C does 100 or so more damage. The RC combo I listed was just something random and cool looking, it's not really an efficient use of a RC. I think the timing on HJC into the j.B might be a little tricky.
Some characters it can only be used in the corner though. Only slightly better for a little more effort, but still slightly better when the opportunity to choose between the two arises.
