If it's about competition, all the platforms OP suggested have that factor. However, the only competitors that I think are able to compete directly can only be Binance Smart Chain and Solana, both of which currently show useful features and solutions that ETH cannot yet have. But personally I still think ETH 2.0 will still lead and be the strongest altcoin in the crypto market.
With the reason being that both Binance Smart Chain as well as Solana are way more centralized than Ethereum if I didn't miss anything. As far as I understand Solana increases decentralization over time, but even then it probably is not as decentralized as Ethereum is and will be.
This doesn't mean that BSC and Solana aren't great platforms. In fact they are outstanding projects. Right now BSC is kicking it, there is no question about that and we will see what happens if Ethereum finally manages to scale. That is by far their biggest bottleneck.
