Starknet is a layer 2 of ethereum and not only that their technology is being used by many top project throughout the industry. Though their community airdrop was controversial and people don't like it also they don't have any unique usecase that separates them from other layer 2. This also can be seen in their user drop. On the other hand ethfi is a eth Liquid staking platform and they are one of the market leader in this sector. So ethfi has better chance of survival than the starknet.
