Or will Eth 2.0 kill all above in the list? But then again Eth 2.0 is like Coca Cola Brand in the Crypto market so there's always a Pepsi like Brand competitor to Eth 2.0 right and if so which Blockchain do you think it will be?
Which blockchain is the Fastest, Cheapest, Most Secure

? Usually this determines the winner right?
Forgot to include most decentralized too, this factor is the most important over speed and fees for safety and security
You can't have decentralization and scalability at the same time. You'd just to sacrifice one or the other in order to meet the needs of certain people. If you're looking for the most decentralized alternative to ETH, then Polygon (MATIC) is the answer. Fees are dirt cheap and confirmation times are blazing fast. I'm not aware of any other platform that is decentralized and cheap to use as Polygon (MATIC) itself. But it's far from "killing" ETH, simply because it lacks a wide ecosystem of dApps and tokens around it. ETH 2.0 will only solidify Ethereum's position on the market, leaving the rest of the other coins in the dust. There's really no competitor that could outmatch Ethereum's decentralization and censorship-resistance. People will decide which blockchain network to use depending on their needs. As long as decentralization prevails, nothing else matters. Just my opinion
