If it's just airdrops like JUP and WEN you can find lots of them in telegram groups, but the airdrop that has the potential to offer rewards as big as UNISWAP is probably only zksync. But unfortunately zksync has no signs of listing in the near future and it looks like the airdrop hasn't been confirmed either. In 2024 I view all airdrops as the same (meaning there is no airdrop that is most anticipated) because I participate in all airdrops and hope to get incentives.
