Ethereum and EOS I think are very promising altcoins, but they both have their shortcomings that need to be addressed. But I can say with confidence that these two altcoins are ideal for investment.
Both of them are just as good for investment so we don't need to doubt it anymore,
but if I have to choose between the two I personally prefer ethereum,
because in my opinion ethereum is far better than eos and also more promising
Yes, ETH is currently better and more promising than EOS. But I also advise you to invest part of the money in EOS.
