How do they compare to the full array? Richer? More black?

Designed properly an edgelit TV will have 95+% of the contrast as an equivalent backlit TV.
The theoretic advantage that backlit tv's have is that they have an array of LED that they can selectively turn off allowing finer grained contrast control. The disadvantage of backlit is that the TV will be thicker and heavier.
For edgelit, it is the newer technology mostly motivated to shrink the depth of a LED TV. However with the more advanced edge lit technology they can do much of the selective dimming that a backlit TV can with an array of LEDs. To do this they generally use a set of micro actuated mirrors to reflect the edge LEDs to the screen. This technology in my TV is called precision dimming. The disadvantage of this technology is that it's more expensive. BUT if you get an edge lit TV I would look for one with local or precision dimming.
Backlit arrays will be cheaper, but they'll be thicker and heavier. Edgelit with localized dimming will have similar contrast ratios but be a thinner TV.
