It's a terrible comparison on all counts. All four Digimon series have been conceived as finite narratives, with a beginning, middle and end. The Pokémon anime may have been conceived as such at the very outset, but I shouldn't have to point out that it's clearly evolved beyond that just a bit since then. This is due in no small part to the fact that Digimon is a limited franchise: it releases a new product every year at best to every few years otherwise. Pokémon is very much ongoing, releasing a new product of some sort every 6 months or so at least.
Furthermore, Digimon as a franchise has no actual narrative source material to work from as far as anything is concerned. The franchise began as the little LCD games and though it became a card game and a few forgotten video games later on, none of those provide any of the narrative source material for an animated production that the Pokémon games do for the anime. This gives Toei's writers and animators almost completely free reign to create their own characters, give them distinct archetypal personalities (the goggle boy, the rebellious brooding loner, the leading lady, the smart guy, etc) and craft an entirely original story to sew it all together. The writers and animators behind the Pokémon anime have no such freedom, but they don't really need it because the games provide all that they need: a hero and his Pokémon travel across the region, defeating Gym Leaders, gaining badges, stopping the plans of an evil organization and eventually taking on the top Trainers in the land. In the games, that "hero" is you, playing as the game's main character. In the anime, it's Ash and company. Nintendo dictates everything else to the animators.
Comparing Pokémon and Digimon, and particularly the animated incarnations of both franchises, is simply indefensible and yields absolutely no worthwhile discussion.
