Why use Uniswap instead of Binance?

I've been hearing a lot about Uniswap and Binance, and I'm curious as to why someone might choose Uniswap over Binance. Could you elaborate on the key differences between the two? For instance, how does Uniswap's decentralized exchange model differ from Binance's centralized approach? Also, what are the advantages of Uniswap in terms of fees, transaction speeds, and the variety of cryptocurrencies it supports? I'm interested in understanding the nuances that might make Uniswap a more appealing option for certain users or traders.
