I adore Ripgrep and use it dozens of times a day, and have for years. It's extremely fast, does the right thing most of the time, and has a useful featureset.
Ack is also nice, I've used that quite a bit too. It has the advantage of being in Perl, so if you're on a "secure" computer (no compiler), you can still use a fast + featureful search tool.
