I think mileage varies among us all. What might be good for you might not be good for me, so forth and so on. I say buy it if you like it, try it out, if it turns out to not be your cup of tea, send it packing. I read rave reviews about the PBC. I tried it, not for me, sent it packing. I like Ford trucks, you may like Dodge. That's just how it goes. Grills are the same. So......take everyone's opinion with a grain of salt. Take what they say as being helpful of course but in the end, just because they didn't like it or have a good opinion of it, doesn't necessarily mean you'll have that same experience with it.
As for the grill grates, it takes a smoking hot grill to destroy them (if I am reading Tee's response right). There was a guy on the Keg forum who opened his vents up all the way to burn the crud off of his and forgot about and ran out for a bit. Upon returning home, the Keg thermometer was pegged, well over 1000° and his grill grates were a blob of molten metal. I just googled the melting point for aluminum and it's 1221°F
So, with that knowledge, I assume Tee's grates made it out fine, just the grill took the abuse. I am fairly confident his grill didn't reach 1221° lol
Good luck with your decision. You're smarter than I am, I buy first and ask questions later
