Homeschooling regularly crushes both public and private school in standardized tests. Even outside of that, they have an excellent grasp of critical thinking. There are isolated cases of poorly socialized kids growing up when being homeschooled. However I have also seen worse out of public and private schools. Think the chronically online, discord and reddit types.

No education system will be perfect. Considering a bunch of poorly funded homeschoolers, with no formal collegiate training in teaching, can best the results of the public and private schools with huge budgets is a telling result
