From a staking percentage perspective? Deep onion as it is currently a 10% stake reward.
For all around best technical with emphasis on privacy/anonymity? XSPEC
I like Deep Onion and I have invested in it since 2017, currently I still keep Deep Onion a lot. It has given me a lot of profit, I really like it because it has a long-term development strategy and I am satisfied with it. I think you Deep Onion will also have new developments in this new year.
