c# - Why would I use lazy ICommand over new Command for each property call?

Question

Why everywhere I look everybody uses the first style over the second one? Is there really big performance hit?

private ICommand _exportCommand;
public ICommand ExportCommand => _exportCommand ?? (_exportCommand = new Command(Export));

public ICommand ExportCommand => new Command(Export);
