"I will be accurate versus second guessing"
"I have several of both and visit both corporate stores on average every couple of months"
"I just noticed that the BGE now has a LIMITED Lifetime Warranty"

Your starting to show your true colors Amigo. Your "facts" have been a lot less than accurate so far.
Suggesting a company sucks because you can't get warranty parts from Lowes when all they sell is some defective no-name knock off is a classic example. laugh
Any one can plainly see both companies use the words Limited warranty. That's not subject to interpretation nor is the fact that any one can contact these companies directly and ask for themselves.
I would suggest any one interested in a ceramic cooker go to the respective brand forums for feed back from other owners who have had actually had warranty service.
Ask how long each company has been around and if they have ever changed their warranty.
Putting the thread back on topic there is a BIG difference between GD or BGE VS Primos in the fact that one brand can not be used to grill with the dome open with out voiding the warranty.
Opining about another brand won't change that.
