EOS and ethereum are best coins for investment. So you can go for them. But in my personal opinion, you can also buy Binance Coin, Huobi, Beam, and Bitcoin. These coins are very much good investment for long term. I am sure these coins will never disappoint you.
The best solution at the moment is just to watch bitcoin, as it will decide where to go altcoins, if it goes up it is worth buying many altcoins that you advised, and if down it is better to continue to watch.
