SJR also has a bunch of corrections to reduce discipline-specific differences in citation practices and a way of weighting certain citations more highly (based on the prestige/impact of source). While I think SJR is much better than impact factor, this might not change within discipline rankings too much because most of these differences between metrics address discipline-level differences.
