The way to go is to have high-trust culture and comprehensive automated testing system. You want developers to behave responsibly and to put all development effort into writing good, reliable code in the first place. I personally prefer pair programming over code review. Code reviews have a lot of downsides but two most important are that you can't get from commit to prod automatically (as there is another inevitable manual step) and that reviewer typically doesn't have enough background/time to perform the review in meaningful way.
