Synthetic vision a la terrain database (upper vid in JE's post) - shows you what was there when the database was compiled, not what is there now, therefore won't know about movable offshore installations /ships, new masts or wind turbines (erected since database compiled). The ultimate alluring trap!
Synthetic vision a la millimetre radar, probably quite good but hugely expensive and complex.
The EVS in the Grand New is (I believe) a lot more capable than the SV that HC refers to: the local operator is very impressed with it.
A better idea in this video, but the only decent images I can find online are in a bl0g, and PPRuNe won't link to the url
for those asking about quoting: press the reply button bottom right in the post you want to quote, then in the resulting url delete the number 1 at the end where it says &noquote=1, press enter and the post will be quoted.
