Currently I prefer Komodo over (removed) but I am not sure if Komodo is really a privacy coin

Yes it will perform as a privacy coin with Zero Knowledge Snarks and Jumbler added to obfuscate transactions at both ends of the transaction, as far as I know no other coin provides this level of privacy.
I wouldn't call it a privacy coin like the one you mentioned though because it is more of a platform with A1 privacy, rather than just a coin.
It will do Atomic Swaps as well as 1 million transactions a second plus it will be Smart Contract enabled soon but saying that Atomic Swaps are performed with Smart Contracts so it is already doing that as a function.
I think you best look at the below, for more you can do with KMD.
