I also have a favourite string matching algorithm, the "Generic SIMD" from this post [1] by Wojciech Muła (I haven't really read the other two SIMD algorithms since I wasn't planning on working with intrinsics).

There were some good comments that post's thread [2], including from burntsushi of ripgrep.
