I have both and use them for different things. As Mark notes above my pellet doesn't do a good job of searing, so anything which needs direct heat goes onto the kettle. Anything which goes indirect goes onto the pellet.
One of the things benefits of the pellet cooker that I don't think gets enough attention is it's use for short cooks 15-20 minutes. Often times setting up the kettle or drum, waiting for the temp to stabilize etc. takes longer than the cook will take. With the pellet I flip the switch, it heats up faster than my oven, I toss on the food, cook and when I'm done I pull it off. No waiting for the fire to die down and no waste. It's a nice way to add some smoke to foods you might not normally take the time to.
