I've always compared Pokémon to other JRPGs like Dragon Quest, Final Fantasy, EarthBound, Undertale, Shin Megami Tensei, etc. I've never been fond of the box people put Pokémon in, where it's grouped in with Digimon, Tamagotchi, Monster Rancher, Neopets, those games just because Pokémon involves pets and collecting. Lots of RPG fans have a weird tendency to look down on Pokémon and consider it an outlier and exception that no one should keep in mind when talking about the JRPG genre so when people group it in with those pet / collecting games it really irks me.
If Digimon fans really really really want to see a Pikachu vs. Agumon matchup, then, fine, but for the reasons I described above, I wouldn't be able to muster up any excitement about it, which I'll readily admit is a very personal view on the matter.
