ETH is quite secure, many years running the network smoothly after the ETC fork, with a team of devs who are probably among the best
The money is in ETH, as are the bigger protocols, AAVE, Uniswap, Eigenlayer etc, and of course the NFTs on ETH are huge

I think the target audience for the two networks is different
