What exactly this combo does that prettier can't?

[ackvf]

I am quite confused by all the different npm packages and the various approaches to set up a project properly.

I wonder what benefits using prettier+prettier-tslint bring and how does it compare to tslint-config-prettier ?

The only reason you'd want this package is if you want custom formatting rules from tslint to take precedence over Prettier. If you're happy with Prettier's formatting you should use tslint-plugin-prettier.
