SVI vs Layer 3 interfaces

Could someone help me explain the situation in which a L3 routed port would be beneficial to using an SVI on a layer 3 switch? I work on a lot of smaller networks with collapsed core that goes Core/Dist switch > Firewall using a stub VLAN with an SVI on the switch. My understanding is layer 2 info gets sent out an interface if using an SVI, but if the device on the other end is layer 3 does it really matter other than more noise on the line?
