Not good tbh.  The best airdrops I've been in are Arbitrum, Wormhole and Hyperliquid.  There are other decent ones that gave out lower than those three but can't remember all of them.  I guess Layer Zero was alright, IO was ok but I'm pretty sure there was another one that I can't remember that paid out well.  It happened when I needed it the most.  This was before Hyperliquid happened.

Anyway, I think the next big one is Monad and the protocols getting built in that eco.  They have a strong community so it's hard to fade those guys.
