As the title says.

The Seoul emitter has a lower thermal resistance than the star version.

In your designs do you prefer touse the emitter and are confident that the bond you make over a smaller area is as good as it can be. Or do you perfer to knowingly sacriface some resistance knowing the bond you make your self is over a bigger area and more likly to be good...especially as the slug is live,

*aspects?

Emitter usually when a nice heatsink is available, especially on a cree.

If you were doing it right you would epoxy a emitter directly to a hard anodized heatsink. The HA will provide the electrical insulation.

Good point about the ano....I forgot ano doesn't conduct.

All of the above, as it depends on the light
