Baro VNAV is all well and good in some instances but relies on having an accurate Baro to put into the box. Whereas SBAS isn't restricted by the need for inputs like a Baro figure nor is it affected by the input of an incorrect Baro figure. If you ask me SBAS is a much better option than Baro VNAV.
