First of all, the dinosaurs don't talk in MoTD unlike in WWD

Second, let's look at the models:

The rosters:

March of the Dinosaurs:

WWD:

Model comparison:

Pachyrhinosaurus

WWD:

MoTD:

Troodon

WWD:

MoTD:

Edmontonia:

WWD:

MoTD:

Alphadon:

WWD:

MoTD:

Quetzalcoatlus

WWD:

MoTD:

Gorgosaurus

WWD:

MoTD:

Edmontosaurus

WWD:

MoTD:

The models in WWD look great and all and I kinda like them better than MoTD, but still, the models still hold up in MoTD

Finally, the story is more accurate in March of the Dinosaurs than in Walking with Dinosaurs 3D, technically a dinosaur version of the Serengeti wildebeest and zebra migration. Walking with Dinosaurs is more cartoony, but honestly, I'm OK with that

So which one do you like better?
