ETH now has another competitor due to insane gas price which becoming really hard for everyone. People are moving towards alternative but demand for big players growing very fast and this is pushing towards the new level. I think other blockchains will give though time in coming days.
What kind of competitor are you talking about? Binance Smart Chain or Huobi Eco Chain? The main problem with these competitors is that they offer to use their ecosystems, which are a fork of Ethereum. We are told that this is DeFi, but there is no decentralization in these projects, because these are centralized blockchains.
Polkadot and Cardano, according to their fan bases. Cosmos coming back around as well.
Cardano will launch smart contract features in an upcoming update. The polcadot has over 300 projects pending launch on the mainnet. But there are no more than 100 places in total. Polcadot network can serve no more than 100 parachains; with their further increase, performance problems in the mainnet will begin. More than 3000 projects are working on the Ethereum network.
The biggest competitor to ETH now is called SOLANA SOL. I been in ETH from the start (check back in this thread to see) and i can seriously say SOL is has the best Blockchain tech in crypto today.

The others rushed to fill a gap by throwing together concepts hoping they stick. Solana devs went to the root of the problem, started from first principles and revisited old research on concurrency.
