One simple and useful way is by being much faster, which is the case for these tools. There are benchmarks linked in the README.
If you have to explore data anyway, using basic unix tools, piping one into the other, always works. You end up with verbose, but readable code.
Put it into a script, make sure it works in a more general case and you might get close to what some of the more specialized tools can do.
