What are the +/- for each one and Why will this one survive?
Maybe there is something that you see and other don't
currently eos is ranked fifth and ethereum is ranked second. and both are almost the same technology. I think however ethereum remains the most superior compared to all atlcoin traded. a little striking on ripples, yes ripples might be the next option.
If there are two choices what coin you will choose, between Ethereum and EOS? The majority choose is ethereum, because of the promising features and already popular especially good for investing. But the best thing to do is choose both.
