The new spirit is a well built grill and will do well for a lot of years. You do give up some of the warranty you get with the genesis. I went with the genesis primarily for cooking area. We are a family of 7 so we need space. If the grease doesn't hit the bars it hits the removable grease tray which makes for easy cleaning. As for the heat Sheila I believe it does two things. First it allows for more efficient heating. Second when grease hits the tray it can splash up to burners and cause flare ups. This should help guard that. That said I have only had flat ups when I cook the high fat content frozen burgers and I don't have the heat shield. That was added in 2011,
