Creating a semantic model directly in Fabric workspace vs deploying it from other tools (Power BI desktop/Visual Studio))

Question

Hi, Let's says we have a datastore (Lakehouse or Warehouse) in Fabric workspace. We want to create a custom semantic model on top of the datastore. What are the main differences between creating the semantic model directly in Fabric workspace vs creating a model in PowerBI desktop/Visual Studio and deploying it to the workspace. Are there any advantages on one over the other. Does the model still use the DirectLake mode if we deploy it from Visual Studio or PowerBI desktop.
