The searing station is definitely a "must have". Just as my old Weber, this grill does a great job of maintaining heat at what ever temperature you desire, but the ability to kick it up on one side for searing beef or tuna steaks does take it up a notch. 
I also like the redesigned grease trap, much easier to access. As well as having the tank outside ... much easier to turn on/off between grilling sessions. The fold-away warming rack is also a plus. 
While this is a very high-end purchase, it does carry the 10-year warranty on ALL of the grill parts. Since I do grill several times a week, grill parts do wear out. My last Weber lasted over 7 years. I have never had a grill that long before. Quality Product!
