Most of the DCC systems available I would call then "standard" DCC systems. EZ command is a non-standard DCC system. It has most of the feature that a standard DCC system has striped out of it. Dynamis is a "standard" DCC system. Most of the DCC system manufactures also offer different level of there systems. This is usually based on the usage/Layout size, Light to heavy (how many locomotives, throttles, Etc it can handle simultaneously). This is just another way to look at the differences.
I sent about a year doing DCC research before deciding which system to go with. My decision was based on future layout expansion plains (Turnout control, block detection with signaling, and some automation with JMRI.)
