In my opinion, random generated elite maps are best and here is why.
1. You don't know what get. (Unless you check the editor).
2. The map is new for both opponent.
3. Saves time to edit a new map (Maps that are edited & saved are excluded).
4. No tampering with the map structure to favor one's own preference.
Here's the disadvantage of an edited elite map.
1. Takes time to edit.
2. Can be edited for advantage (Theory).
3. Can be played more than once by player (Speculation).
4. Maps can be quite complex and lead to camping.
