No, it has a different purpose; VS Code extension and the former ADS are targeted for development, while SSMS is for server and database administration. I am a heavy user of SSMS and can do everything I ever need there, I don't use the VS Code extension for MS SQL even if I have it installed and I use VS Code quite a lot. This is because I am also acting as a backup and supervisor for our DBA team, so I am involved in DBA work.
