They don't have the same goal. Here is a good resource to start researching on coins. You can compare their algos scores that the platform has gathered based ontheir analysis.
https://coincheckup.com- EOS is running on the Ethereum Blockchain, and has an centralised organisation structure. I cannot talk much about their project because I am not familiar with it.
- OmiseGo also is a ERC20 token running on the Ethereum blockchain.
- Cardano has its own blockchain, is semi-centralized, has a multi-layers architecture ideal for scaling and to avoid congestion, will be fully decentralised next month/May if all goes well, and plans to be the blockchain of blockchains later in the year /early 2019, by enabling blockchains to be able to talk to each other.
I can go on all day long about their project and quote you the multiple advantages of their elegant Haskell code, but if there are 2 things you should remember, it should be the following:
1)
The IELE Virtual Machine (VM) they are building that will act as a universal translator for ANY K-defined language, K being a framework that they built (Here is the full list
https://github.com/kframework) (Java, JavaScript, Python, Solidity, C etc...). What does it mean? It means that developers won't have to learn Solidity to be able to write smart contracts (SC). They will be able to write SC in the language they are the most comfortable with, and these SC will be translated by the IELE VM to be readable by the Haskell protocol...We're talking about Ultimate Compatibility here. It's beyond important for this industry.
If they succeed and that's why they hired Philip Wadler, the co-inventor of Haskell among other brilliant minds, how to put this, they will be considered as the go-to platform for Smart-Contracts. I would go as far as to say that Ethereum will look like a toy due to its limitations (and I am invested in Ethereum)
Note: IELE is built by RunTime Verification, which Cardano/IOHK funded. They have the NASA and DARPA as clients. https://runtimeverification.com/blog/?p=498
Runtime V are not exactly a bunch of kids in their garage like other coins.
2)
Sidechains: Read this article to understand why Cardano will be considered the blockchain of blockchains, meaning that a BTC or a ETH or any other coin will be able to navigate on the Cardano blockchain....
