While complicated, Bitcoin's implementation isn't nearly as complicated as Ethereum's. The main reason might be attributed to the fact Bitcoin scripts don't have for loops and Ethereum does allow looping and other more complicated operations. That Ethereum seems superior is just an effect of marketing and language around their scene. It helps they have people who can quickly say seemingly smart things (think GPT-3) that no sane person can parse in a short amount of time to arrive at knowledge. The system is overly complicated for a single individual to understand and trust easily. It may well be very difficult or impossible to tell if a given contract is secure or not. In reality, there are very few mainstream "killer" use cases being served by Ethereum, although they do entertain themselves by trying to "break" each other's contracts. The most famous case was when the authors of Ethereum rolled back the chain to get their own coins back from a clever "hacker". The fact is, that individual followed the rules and still lost the coin they were due them by contract! That's not happened with Bitcoin, at least on mainchain.
