The commands are functionally equivalent, as when zsh is installed, it is generally placed in a dirctory on `PATH`, however, `pacman -Qi zsh` only works on Arch Linux-based systems, and as such, is less portable than `zsh --version`. You may also use `which zsh` to get whether an executable exists on `PATH`.
