Most search engines use similar algorithms, so it's natural for the results to be somewhat similar. However, the key concern is whether they are prioritizing ads over content value, and as far as I’ve used lexy, they are doing pretty well, especially considering they are newly starting.
They're literally scraping Google on the backend and returning the results to the user as if they invented a new search engine. The links are exactly identical to Google's, in the same order.
obv they will be identical that is what i have explained you above main thing is providing what you want , eg if you search for dogs every search engine will show you a dog , you cant expect it to show extraketchup hotdog just because its new search engine
