I am interested in expanding my investment portfolio and have found some interest in interchain operable projects such as polkaDOT and COSMOS. I have really only looked into these 2 options as the market caps are in the range of where I would like to invest, meaning: significant funding for development, large community support, institutional interest, room for price growth.

One of the most attractive parts of these projects is the staking rewards, and seemingly endless airdrops. It almost seems like a no-brainer to get involved in one of these projects now that the crypto winter is coming to an end. Staking APY along with price growth is unreal: Dot ~ 11% and Cosmos ~ 20%.

I currently am leaning towards Cosmos because, on the surface, it seems to offer better rewards: double staking rewards, airdropped projects like Celestia...
But something has to be going on for polkaDOT as the marketcap is nearly 2X that of Cosmos. So I am obviously missing something.

Anyways, I am looking for input from the community.

Which one do you believe has a better potential?
What are the pros and cons of each?
Or simply, which one would you choose and why?
