Electroneum for the short term, Sumokoin for long.
Electroneum has great optics, and a good plan to get as many eyeballs at it very quickly through a mobile miner, which they pad with pre-mined coins to get as much consumer and general public awareness. This is likely to happen in a few months, and I suspect Electroneum is planning to use this uptick in value to finance tech development (something they appear weak in).
Sumokoin is a young coin, and a fork of Monero. So far they seem to be very technically competent and have quickly created an Android wallet. They haven't missed a deadline in their clearly laid out roadmap and have had little technical issues in the way. In time to come they may rival Monero, but for now they supplement the coin.
