I considered both too! If I had gone into social work, I wouldn't have needed an extra year of school to get my second bachelor's in communication disorders. I also feel like social work is very flexible, and there is a lot you can do as a social worker! Ultimately I decided to go into speech pathology, mainly for the higher salary. I teach now and didn't want to go to grad school for two years to make a lower salary than I make teaching! I also felt like I didn't have the super caring, calm, empathetic demeanor that good social workers have and so ultimately wouldn't be good in the field. There are pros and cons to both though. Just think about what you really want to do more!
