Though I don't think Burgers should win this round, I think it deserves more credit than a 3-0 implies.
For Elephants the enclosure is far superior to the open sandy deserts with steep moats, that Berlin currently has. The enclosure in Burgers might not be very large, but it is one of the better structured and most forested Elephant enclosures around. Burgers' functions as a retirement home for geriatric females and for that the enclosure is perfectly suited. These animals are often not wanted and few zoos specifically keep them, Karlsruhe and Neunkirchen are two other examples.
Whereas in Berlin one can see all 6 equid species, including 3 zebra species, Burgers' keeps only one. Their Grant's zebra group is however the largest in Europe and in terms of behaviour is very interesting. On their multiple hectare savanna they keep 3 harems + a bachelor group together, which gives an interesting dynamic.
The savanna is also home to the largest White-bearded wildebeest herd in Europe, as well as one of the largest groups of Giraffe. The White rhino group is one of the most successful in terms of breeding with 10 calfs born in the past 17 years. The Savanna enclosure also holds breeding groups of Ellipsen waterbuck and Roan antelope, as well as a few Beisa oryx. The days of Hartebeests are unfortunately over, but it is still one of the better savannahs and all animals actually occur in Kenya (though ranges don't always overlap there).
My favourite hoofstock enclosure is a large mixed species enclosure with Banteng, Hog deer, Eld's deer, Muntjac, Pig-tailed macaque and Siamang. It is highly unlikely to see primates mixed with hoofstock and even rarer to see it in an Asian setting. The primate - hoofstock interactions here can be very interesting and there is always something happening. Berlin really has nothing to offer on a similar level.
The forest reindeer are now relatively common in Europe, but back in 2002 Burgers was the 2nd zoo outside of Scandinavia (after Bern) to receive this species and in 2005 the first outside Scandinavia to breed them. Breeding succes in Burgers and a few other zoos made it possible for this species to spread. Burgers is also the only reason why there are Bighorn sheep on the continent, with all animals coming from here.
In terms of conservation Burgers' does not specifically protect a single species, but it has been managing a rainforest reserve in Belize together with Kerzers for the past 30 years.
Baird's tapir are one of the flagship species there.
