Both coins are good. In NEO, I advise you to invest in a long term and advise in ETH to invest and hold coins until the end of the year.
Do you really advise? And if Neo or Eth will be zero then do you recover the losses from such advise? Neo is not better Eth imho. It has enough limitations and errors. And for long-term I don't sure that Neo is the best. You can compare more exact because of such advice can play the bad joke with reputations
