HZ has a team of developers who stand behind their work and don't hide their identity. They have collateral on the line (their reputations). They have great branding and a fine marketing team as well. It has an Asset Exchange and will soon have a reputation system to accompany it.
The devs have plans of building a smart-contract system and anonymity features. It has an official partnership with Blocknet (the internet of blockchains, merging multiple "coins" and their associated tech) and Bitnation (governance 2.0) Both of these have huge potential for real world use/adoption and advancing the crypto-sphere and eventually bring about society 2.0
HZ has better qualities than NXT (anon devs, no new releases/partnerships, bad distribution, etc...) and has a much lower price and marketcap.
I don't actually see any profile on their website. The team pages seem to be offline when the index isn't. How creative.
They however are starting to rise up, I noticed them when i tried browsing which coin can have its potential in the next years and they could just be one. But we'll see if the development is further pushed.
I have been following HZ since early days and have held much of it for a long time.
I just believe it has a good chance to be big even though they keep a low profile.
