Using my property manager to sell my renal?

Just curious how competent are property managers are in selling properties - especially rentals with tenants in them. I mentioned to my pm that I may sell 1 of my rentals. They said they have a brokerage  and could represent me, and also had tons of investors that would be interested. On one hand, it makes sense to use them since they already manage it and I wouldn't be selling to home buyers. On other hand, I wonder if it's any better to use a real estate agent dedicated to buy/sell? But does that even matter?
