What are the pros and cons of each of the cryptocurrency mentioned in the title?  ???

Ethereum is a decentralized platform that runs smart contracts written in Turing complete programming languages such as Solidity. Ether was created as a cost for programs to run in Ethereum.
Pros:
Ethers will always be needed to execute code on Ethereum, and most projects nowadays are built on top of Ethereum, which makes it the best long-term potential cryptocurrencies.
Cons:
The value of Ether ties to the success of Ethereum. It is possible that it can be replaced by future blockchain projects with similar features. One example is the NEM project(covered later).


Ardor
Ardor is a public blockchain platform that will allow people to utilize the blockchain technology of Nxt through the use of child chains. A child chain, which is a ‘light’ blockchain that can be customized to a certain extent, is designed to allow easy self-deploy for your own blockchain. Nxt claims that users will "not need to worry" about security, as that part is now handled by the main chain (Ardor).

Pros:
Both Ardor and Nxt offer convenient online wallets, including Android Freewallets. All technologies related to Nxt, Ardor and subsequently IGNIS will allow swaps between these tokens.
Cons:
storing and holding is a somehow technologically involved process. You require a Nxt wallet, and then wait around for the Ardor snapshot to move into a different holding structure.
I think this information should be useful.

The pros are more about the business structure and adoption than about the technological base. Chains can be changed, improved and adapted, but the massive amount of Ethereum tokens give a big advantage to this chain.

wow, for the first time I heard about such a coin. I read a little about this technology. On paper looks good. Particularly I liked that the collection of commissions for transactions will occur in the tokens of the chain where the account was created.
