Cardano network clogged, Avalanche congested a while ago, Polygon almost stopped completely due to some flower picking game. Are these really going to work as an alternative to Ethereum with its high gas fees?

Before anyone goes nuclear I will say that ETH is too damn expensive. But are the alternatives really so much better?

Recent news about Cardano congestion shooting up around 90% and more, Polygon being borderline unresponsive during Sunflower popularity/incident, and AVAX fees getting sky high while network suffered congestion a few months ago.

If these networks had the Ethereum levels of activitynon them, they wouldnt hold for long. Cardano has a handful of dapps and its already clogged? Same with Polygon. 1 dapp putting whole network on stop is really not what people would expect of the so called "next gen eth competitors."

While I 100% agree that gas fees on Ethereum are absurd, I wonder if the alternatives that we have at the moment in top10 are going to solve that. All claim insane TPS and finality times, but when the shit gets real, the fees and network congestion go up to the sky.
