Why is Avalanche better than Ethereum?

Could you elaborate on why Avalanche is considered superior to Ethereum? I'm particularly interested in understanding the technical differences and how they translate into real-world advantages. For instance, does Avalanche offer superior scalability or transaction speeds? Does it have a more robust consensus mechanism? Moreover, how does Avalanche's approach to decentralization compare to Ethereum's? I'm also curious about the types of applications and use cases that Avalanche might excel in, compared to Ethereum. Could you provide some concrete examples to illustrate these points?
