Why Avalanche over Ethereum?

Could you elaborate on why Avalanche has been gaining so much popularity over Ethereum? I've noticed a significant surge in its usage and adoption recently, and I'm curious to know what specific advantages Avalanche offers that might be attracting so many users? Is it the scalability, the transaction speeds, or perhaps the cost-effectiveness? Could you also compare the two platforms in terms of their security, decentralization, and overall ecosystem? I'm interested in understanding the key differences and similarities between Avalanche and Ethereum to make a more informed decision on which platform to invest in.
