Consumer Reports has ratings of all sorts of Grills, though not build-in models ($10/month digital).

What makes this grill better than others?

Have you looked at pellet grills? They result in much better flavor than LG/Propane, especially for BBQ.

MAK is often considered the best but there are others that are quite good.

Avoid Treager and Memphis (Memphis was once quite good but quality is totally tanked the past 2 years).

@opaone, I have a recteq pellet smoker which I LOVE! So much better than Traeger. However, we are looking for a drop in BBQ grill; the smoker will be off to the side as a stand alone.

@Daria Sweet, the salesperson claims the burners are better and the stainless is a better quality. Price for the Delta Heat is less than the Weber.
