Bertha is the Ground type Elite 4 member in the games Diamond, Pearl & Platinum. Where her team consists of Quagsire, Sudowoodo, Golem, Whiscash & Hippowdon in Diamond & Peart, so this team just bring a good Grass type and you basically have that battle won, with 3/5 of Bertha's Diamond & Pearl team being 4x weak to Grass. Then Bertha's Platinum team is Whiscash, Gliscor, Hippowdon, Golem & Rhyperior, where with her Platinum team, it's best to bring a good Grass type for the Whiscash, and then a good water type with ice coverage, as you would want an Ice type or Ice type move to defeat the Gliscor a bit easier. I am going to admit though that Bertha is definitely my favorite member design wise from the Sinnoh Elite 4, and honestly, she is my favorite member to battle against, even if she isn't exactly the toughest member. Overall though, I just felt when looking at teams of the other members still left in my ranking, alongside design & how much I enjoy them in general, that Bertha was the best fit for 9th place.
