The difference is TFM doesn’t pop up in my face without me asking for it while I’m trying to do something basic.

Yeah product tour is like a popup or cookie banner you just wanna close that shit down. It is something that seems like a good idea and maybe even required for polish, like a 3 column pricing page and an oauth login, but think we are better off without it.

Instead add the killer feature: a feature search box ala Google Docs.
