Looking at the specs on AB's website, the "HC" version is designed for applications where relatively high current is required, such as powering relatively large monitors, lights, or a big (full-size shoulder mount) camera loaded with a ton of accessories.
Refer to the details on the product pages:
http://www.antonbauer.com/Products/DIONICHChttp://www.antonbauer.com/Products/DIONIC90I should mention that one reason why I'm staying with AB batteries is because years ago I bought one of their chargers (a Titan 70, which I love), and because they are relatively expensive, I want to keep getting use out of it until it dies, or until it's no longer compatible with AB batteries, or until I die, whichever comes first (hopefully not the latter).
Point is there are many different reasons to use one brand of battery or another, and meanwhile times have changed: Years ago there weren't very many choices available for brands of "pro" camera batteries & chargers. Now there are dozens, many of which are very good, and some much less expensive than the original "industry standards".
If I were buying new from scratch, I'd seriously consider one of the less-expensive v-lock battery systems designed for use with more than one camera via different cables, rather than a camera-specific battery designed to mount on just one camera. But the latter type of battery can make a lot of sense, too. Depends on what features are important to you & your budget.
