Although you posted a disclaimer that your topic should not be about a single cryptocurrency, I'ld have to point out NEM is the one which fulfills all your criteria and it is currently in the top 5 of currencies on coinmarketcap.

1. NEM was a wide distribution to 1000s of stakeholders and only around 65 BTC was collected. When R0ach and Spoetnik call ICOs scams, they're almost always referring to stuff which collects millions of dollars and is distributed to a few.
2. NEM is Proof-Of-Importance
3. Proof-Of-Importance
4. NEM does not have a voting system. At one time NEM considered it, but there were a lot of disasters then with other people's implementation and even now. Bitshares' issue was it was very hard to kick out apathetic / inactive delegates. DAO, before the hack, was only able to get around 20% participation.
5. Proof-Of-Importance.

These are threads I have seen a lot on Bitcointalk. People saying we need a fair distribution or an alternative to PoW/PoS. NEM already had you all beat since 2014 and now it's a top 5 currency. NEM is still cheap so the time to buy is now.
