Whether smart case is enabled by default (as ag does) could easily go either way. Notably,.I think having it disabled by default is a better UX. But ripgrep does have a --smart-case flag, which you can add to an alias or a ripgrep config file. It also works more consistently than ag's smart case feature, which has bugs.

See my other comments about perf difference. And ag has several very critical bugs. And it's unmaintained.

If you only search small amounts of data, then even a naive and very slow grep is likely just fine from a perf perspective.
