The Ethereum ecosystem has more developers not just than any competitor, it has more devs than every other smart contract platform combined; excluding bitcoin it has more devs than every other crypto combined.

The result of all those developers is innovation. Every advance in DeFi has happened first on Ethereum, other chains have their own dApps but they are almost exclusively clones of things that were developed first in Ethereum. The amount of value locked in DeFi just on mainmet is double that on every other chain combined.
