It's not clear from the README what advantages it offers over ripgrep.

Whait what's that? I'm stuck with ag and {a..z}grep.
BurntSushi (dev) built a grep replacement, `rg` (ripgrep), in Rust, that tends to run circles in terms of speed around grep itself and other grep replacements. The UX is also pretty nice. I install it everywhere now.
I'm curious (like others here) how `rak` is better than `rg`.
