Always aim for BTC, higher chances of getting ROI and has the most potential out of all the coins out there. But those altcoins you mentioned are good as it has good progress over the past few months. You can also look at IEO's with projects that improved themselves like being more decentralized than EOS. As for me, I have 50-60% of my portfolio in BTC and the rest are scattered on ETH, and other good altcoins.
