Ethereum 2.0 is a development from before, so many additions are made to improve what they don't have, but Ethereum will continue to be the monopolist around this place, while Matic is different from ethereum, although the way to use it is easier and cheaper, but Matic is not can provide fast transactions like ethereum, if you compare the two, then ethereum is still the choice for now.
While blockchain has smart contracts and technologies that enable token transfers at ERC 20 that are closely tied to this, there are both positives and negatives to the results of using anything in the crypto space, depending on how we can minimize the risk caused by anything.
No doubt ethereum will continue being the monopolist over other networks but will continue having complications which will eventually trouble users of the ETH network and this is what have really brought the rise of ETH competitors, and even the ETH 2.0 hasn't even shown any much effect, but well I think in all of the projects mentioned above Near protocol seems to be unique among all, instead of being a competitor! They more like a compliment to ETH which is they render support to the short coming of the ETH network.
