Why do you want to know another platform to compete with Ethereum? Actually, you don't need to ask this, just monitor the development of several platforms that potentially become the competitors of Ethereum. For example, you can take a look at Binance smart chain, Tron chain, or Polygon chain. These chains can be the strong competitors of Ethereum in the future. Just monitor them, then you can conclude how far they can be great competitors of Ethereum now.
Maybe because the High Gas fee of ethereum when congestion happens that's why he is seeking for option when things happen again.
