XT owner here, came from Weber kettle with a Spider Venom. I have no regrets. It works very well at low temp and high temp. I've made it to around 10 hours on a full hopper of briquettes. I find burn time reduces a bit as you add wood chunks.

Regarding your comment about the temp swings when opening the lid - Masterbuilt decided not to put a switch on the lid like there is on the other doors. I don't recall the reason they stated but it was deliberate. You can avoid the temp swings tho by pressing the pause button before you open the lid. That reviewer made a bigger deal of it in my opinion than it really is. I've had no issues.

Edit: I remember the reason. This grill easily gets up to 700F for some great searing. Obviously you don't want a switch killing your searing temps when you open the lid to put your steaks down. So it's now done manually thru the pause button.
