Why Ethereum is better?

Hello, I am a newbie and i want some questions answered. I have tried to watch youtube and get some answers but it's a lot of information to process. So i am asking them here. Please answer them in the simplest way possible. 1. Why is ethereum better than other projects? 2. what are other crypto currencies out there which has a lower transaction fee and why shouldn't i use them instead? 3. What are smart contracts? Please give me a real life example? 4. Who decides the transaction fees? 5. Does eth transaction fails? What happens to the fees and crypto when it fails? Why should a transaction fail on the first place? 6. What happens if i put wrong wallet address which doesn't exist? 7. How do wallets make money? Do they charge their own fees + transaction fees? 8. What makes one wallet superior from other? Which one should i use? 9. What did EIP-1559 did for ethereum? 10. What are the benefits of Ethereum 2.0?
