I would choose eth than eos at the moment because its more profitable and better than eos. Much more stable and always increasing the value has made eth become more demand.
i must prefer ethereum because this altcoin is good for long term even its hold or sell. etherum is one of best among in any altcoin now that's why ethereum now is a second large cryptocurrency next to a bitcoin. by being popular and demand many people having an interest to invest in ethereum because of the good value in the market and the profit that we received in ethereum.
