Both have birds and reptiles and different types of Mammals which made them well balanced but i still think NA was peak animal pack. It was perfect for the theme it was supposed to cover and we never had a pack with that good choices after it. Because even in Grasslands and Wetlands i can think of better picks for some animals. Oceanía came close but is missing the tree kangaroo in place of the random quokka so in a way it was also a dissapointment.Both the animal packs that year were great grasslands is still my favourite even though it had 3 carnivorans the roster just felt really strong especially the exhibit animal. Grasslands alone had representation from every continent and all but the aquatic biome. I may be biased since I like grasslands as a biome more than wetlands but both are good.
Only thing about the North América Animal Pack that would've made it a 10 for me would've have been a bird, the most iconic possible after the bald eagle: the turkey. I do prefer other choices like roseate spoonbill but the turkey is an icon among NA birds and is really the only thing missing from that pack and i'm sure that if the arctic fox would've been in the arctic pack the turkey could've been in the animal pack.
