I'm referring to which platform is "best" when it comes to handling high-performance transactions at a fraction of the cost. Without a doubt, Ethereum is the best platform in terms of decentralization/security/reliability. But it fails miserably when it comes to handling massive transactions per second. There are many alternatives on the market aiming to be the best platform for "De-Fi". Ultimately, there can only be one winner.
As much as I like the diversity of smart contract platforms in crypto/Blockchain/land, I'd say the market is oversaturated. So many cryptocurrencies with smart contract features would be too much for the industry. That's the downside of everything being open sourced and decentralized. Maybe fierce regulations will slow down the presence of new smart contract platforms on the market? At least, everything is working as it should. Who knows what the future holds for "De-Fi"? Just my thoughts

I can agree with you on the part the crypto market is over saturated with different smart contract projects but it is equally good to have several in other to be able to have options when one or two are not performing up to expectations. Take eth situation as a good example, eth is unable to handle massive transaction and also have a high gas fees which makes bnb, sol, matic a good alternatives.
There is a possibility that these 3 mentioned are not the best among them, may be there are others who are yet to be known, it is good the market is open source and not tied to a particular few where there will be no alternatives.
