Is simplex better than Coinbase?

I'm curious to understand the differences between Simplex and Coinbase, as I'm looking for the best platform to use for my cryptocurrency transactions. Could you elaborate on how they compare in terms of security, fees, ease of use, and the range of cryptocurrencies they support? Are there any unique features that one platform offers over the other that make it stand out? Ultimately, I'm trying to determine which platform is the better choice for my needs and investment goals.
