This replaced my Weber Silver Summit that lasted 16 years. Grill capacity of Genesis II a little larger. Stainless steel a good look but I rather have side shelfs of another easy clean material. 
The negative is shelf space is very small even without side burner. I liked the pull up side shelfs on prior design that added just enough outside area to hold food or utensils when it was needed which I used most times. Also the open shelves under grill should have a backing as most items placed there fall out if not properly placed. Finally some hot spots are apparent that require your attention when cooking to avoid uneven preparation
