Gen 3 was okay.
But man, the OST is something else. I know it's memed to death because of all the tooting but the compositions themselves are just phenomenal.
The credits theme is probably unironically my favorite song ever and I don't mean video game music I mean favorite song period

I think gen 7 would eventually go on to be a better version of gen 3 in a lot of ways.
