You're forgetting ZERO, SUMO and last but not least Spectrecoin. Spectrecoin has an interesting roadmap ahead and don't forget. Default stealth adresses, default ring signatures, in-client TOR + OBFS4. Stealth-staking is still to come. So that's at least 2 unique feature (TOR + OBFS4 & stealthstaking) this coin has to offer over al the others.
