I heard a story about new ETH couple of times. Each few months we have 'new ETH", ADA for example was ment to be new ETH.

ETH has:
1-community
2-brand
3-use cases being build by years (f.e. uniswap)
4-infrastructure (f.e metamask - well amost every wallet support eth, pay with eth on many sites)
Dot has:
1-overhyped price
