EOS has some very nice improvements such as faster transactions and syncing, but ETH has been around since 2015 and is widely accepted and established. I'd stick with ETH.
Yes you are right. EOS is a very good coin, but ETH is already a working platform on which a lot of ICO was launched. But I hope EOS will develop.
Of course it will develop like with billions of fund raised it will surely be but yet it all depends on how the team eagerly work. But personally, eth is the present and will be the future if eth will resolve its issues. Moreover, I'm keeping an eye to eos on how it develop its blockchain and I think everyone should.
