I'm not saying there's no lock-in, just that it's not as rigid or strong. Better search results (for you) is exactly the kind of reason you want to be using one

I'm not saying there's no lock-in, just that it's not as rigid or strong. Better search results (for you) is exactly the kind of reason you want to be using one search engine over another. If another search engine started providing better results, you'd be able to swap, and the only effect would be the psychological disorientation from the change interface (I struggle to use DuckDuckGo because my eyes scan the wrong part of the screen while trying to take in the results).
