When I was a kid I refused to watch digimon at all. I still do today. Since I didn't watch digimon, I watched pokemon. It was one of my favorite shows when I was 10, I got the collectables, the games, plushies, whatnot, and then came the tournament. I HATED that Ash lost the tournament, and even losing as far back as the 4th heat. Fuck you pokemon animators. (Also, fuck you again for making Ash get rid of Butterfree, you dicks)
After that I still watched (with anger of course, a tiny flag with a declaration of war in hand and drums in the background) but eventually got bored of it completely by the time the pokemon movie with Entei was released.
So, my child self will say pokemon, my modern self would say neither.
