Is there a code difference between using custom library blocks vs custom toolbox blocks

I've been told that I can create a custom toolbox with custom algorithms. I currently use a custom library for those custom algorithms blocks. I've been told that the reason for a libray is to reduce the code generated by using the same library block multiple times in the model. This would be achieved through the use of a function call for that block. If that block is in a toolbox and used multiple times in a model, would the generated inline code be larger due to that block code added multiple times or the same as if that custom block were pulled from a library?

For generated code size to be the same as when library blocks are used, the Toolbox blocks should be designed keeping in mind more reuse & configured for code generation.
