Popularity-wise, yes. Gen1 and 2 were the "golden age" of Pokémon, when everyone and their mothers were into the games, the cards, the merchandise, the anime, ect.
As far as the games and the pokemon themselves... absolutely not. The newer games are MUCH better than the older ones, and whether pokemon designs are better or worse is pretty much entirely a matter of opinion, because the overall quality hasn't changed much.
