Personally I find Navi better to use for the purpose of “not having to remember commands”. It also provides a description of the command, fuzzy search, and essentially pastes the command in the current terminal, not having to think about current directory or user.
Just is essentially a collection of aliases, while Navi is a collection of pre-written commands in full length (with optional description).
