Grid leds vs Fewer high power Leds, both have different usage, high power LEDs are coupled with different optics that focus the light at different angle, smaller angle make light go longer distance but much concentrated so it may "burn" closer objects making them "too white" (also depending on how the camera can handle such contrasted situation).
"old style" Grid Leds produce shorter distance light but "smoother" and wider angle, so all depend your need, for example for closer view I would use grid leds to not burn people faces, or use wide angle optics for high power leds, but again, the camera ablity to handle those mixed light conditions may vary between models/constructors.
