New mons just look like fursona characters with jobs and their own very defined personality, i can't even picture there being more than one Incineroar or Cinderace or Intelleon, they're too overdesigned and unnatural/human looking

Old mons were actually believable as being monsters/creatures in a broader setting, like something that exists in an ecosystem and that you could run into randomly, like there could be multiple of them distinct from eachother
