Which seller agent should we choose

We have a friend who’s a realtor, but she doesn’t know the market we are in at all, we bought our house with her 8 years ago and that’s the last house she bought in our area. Or we can choose one of the agents that specialize in our area.

Is there downside to choosing a local agent? They would be well connected to many buying agents, and be able to tell us which agent is reliable and by proxy which offer seems stronger, but maybe they will try to push us toward one of their buddies for their own best interest vs ours?
