I don't remember why I didn't switch from ag, but I remember it was a conscious decision. I think it had something to do with configuration, rg using implicit '.ignore' file (a super-generic name instead of a proper tool-specific config) or even .gitignore, or something else very much unwarranted, that made it annoying to use. Cannot remember, really, only remember that I spent too much time trying to make it behave and decided it isn't worth it. Anyway, faster is nice, but somehow I don't ever feel that ag is too slow for anything. The switch from the previous one (what was it? ack?) felt like a drastic improvement, but ag vs. rg wasn't much difference to me in practice.
