Deploy Database with SqlPackage.exe or Microsoft.SqlServer.Dac.dll, any difference or benefits?

问题

What is the difference between using Sqlpackage.exe and Microsoft.SqlServer.Dac.dll to deploy a database? Is there any benefits? We are just trying to deploy a database to localhost. Just curious if Sqlpackage exe has more options/functionalities than Microsoft.SqlServer.Dac.dll, or does it really matter at this point?

SQL Package:

SqlPackage.exe /Action:Publish 
   /SourceFile:"TestDatabase.dacpac"
   /TargetServerName:"localhost"
   /TargetDatabaseName:TestDatabase

Microsoft.SqlServer.Dac.dll

add-type -path "C:\Program Files (x86)\Microsoft SQL Server\140\DAC\bin\Microsoft.SqlServer.Dac.dll "
$dacService = new-object Microsoft.SqlServer.Dac.DacServices "Server=localhost;Integrated Security = True;"
$dp = [Microsoft.SqlServer.Dac.DacPackage]::Load("C:\DatabaseTest.dacpac")
$dacService.deploy($dp, "DatabaseTest", "True")
