Can someone sort out all the EVGA 1080 Ti models?

I have read their website and specifications but I'm still a little unsure. At times, the differences are so minor (ex. minor difference in clock speed, one has ICX cooling while another has ICX technology, some are "elite", etc) that I wonder if I'm missing or not understanding something.

• What do these things mean?
• How are the cards organized in their product hierarchy?
• Are there some models that are most often recommended above others?

Had wanted a Vega, but it looks worse and worse as the days go by. Any helpful pointers appreciated!
