Both feature a boy going on an adventure with one more monsters where they have to gradually battle stronger and more sinister forces to save their friends and the area theyre in. Both also feature powerful rivals, and both also have nods to their games and anime version.
For the record, most fans agree the Pokemon Special manga is vastly superior to the anime by the way. And personally, I think the Digimon manga is on par with the first season anime in its own way.
Anyway, the last similarity is the Pokemon and Digimon monster universes and the evolution and partner stories together.
