I had a Weber propane for years. It excelled at cranking up to 500 or 600 degrees in 5 min. Good quick cooking and good for steaks/hamburgers.
I now have a Grilla Grills Silverbac pellet grill. It heats up slow as heck (20-30 min to get to 500) so I'm not nearly as happy with quick cooking and searing steaks/burgers. This grill excels at low, steady "smoking" type activities (ribs, pulled pork, chicken). Set and forget the thermostat. Mine didn't initially put out as much smoke as I expected so I added a cheap smoke tube off of amazon and now I'm good to go.
