If adoption just your point to justify the ETH then there is a lot of blockchain out that has much better feature than yet ETH still on the top. What do you think is the reason for that? Adoption, feature? Of course not its there reputation as first smart contract blockchain is the only thing keeps ETH alive despite the slow speed and high transaction fee which other blockchain already solved while Ethereum is 3 years behind in terms of tech.
You say that: "Ethereum is 3 years behind in terms of tech", but what projects do you compare?
With a binance smart chain with 24 validators?
https://stakers.info/The Tron ecosystem is very fast, but it is also a centralized system where most of the validators belong to the project investors.
If you look at all the known blockchains, there are few really decentralized ones: Bitcoin, Ethereum, Monero, Litecoin. POS blockchains are centralized, and ethereum developers are trying to make their blockchain as decentralized as possible.
