Maybe it's because they've increased the security and cleaned out the code compared to red and blue? Anyways, I don't play Pokemon for the glitches, I play it for the storyline and the cities.
Personally, my favorite is the Gold and Silver version, and also the rebooted Soul Silver versions. Gold was revolutionary in that the time of day in real life affected how things look in game and what Pokemon you could catch. It was more realistic and immersive.
