HCL is one properly nested format and much more readable like YAML. TOML ends up getting confusing once you nest a few levels.

HCL also has expression evaluation however: TOML parsing is guaranteed linear over the size of the file, but HCL isn't necessarily because you can trivially do things like dynamically create a n*n-sized list from n-sized input list, which may be an undesirable property!
