I agree HIGHLY with the first post. So I believe you should do your own research and figure out which best fits what you believe will do best.

If I had to choose of those four, I agree with everyone else ETH is a good long term investment, but I would only put a certain percentage into it. To make money & lose money fastest, I would place between 50-85% in ETH for long term and then gamble the rest in altcoin trading.

I did the same thing as I stated above and the altcoins have turned a nice profit quickly as I expect my other (ETC/BTC) long term to increase over time.

But overall it depends on what you want to do and how you want to spend your money. Be careful on altcoins hype, NEVER BUY HYPE.

Good luck.
