From my own experience I can tell from all the airdrops that I know the top projects were only: Vite, Ontlogy, Dfinity. All others were shitcoins

Vite, Ontlogy, Dfinity. Sorry, I dont know about the three projects you mentioned. Have they ever airdropped? The well-known airdrops I know about bitcointalk are DeepOnion and semux. For other airdrops I don't know much about.
The current airdrop is really bad. I don't know why there are so many people who are passionate about airdrops every day. In my opinion, the airdrop is dead.
