Gen I lays the basic foundations of what is to become a vastly popular RPG series. For what it was worth, it was really good--there were a few flaws, sometimes caused by glitches (like ghost type not being effective against psychic type). A lot of the pokemon were good--so it's kind of sad that most current pokemon are better (as far as I know) in terms of stats and movesets.
Gen II was my favorite generation. I will admit I hold slight bias because my first video game (ever!) was Pokemon Silver. But, the starters were all so fun to use (Cyndaquil <33). The routes were so fun, and, somehow in this game I felt the most... immersed. I don't know, something about the way the game was, the graphics of the time, etc., gave me a real feeling of immersion and adventure. Most of the new pokemon were really cool, and they utilized a tried and tested method of marketing: nostalgia. But they weren't just like "hey, here's Kanto, have fun!" They put some thought into it, and the ultimate showdown with Red made me feel epic. Also, the music... The champion fight music was so awesome, and the music that played for the Lake of Rage... I don't know, it just makes me really happy and nostalgic thinking about it. I personally don't take to the objection that the story was nothing special--pretty much every pokemon story was pretty bare bones, because it was always mostly about becoming a pokemon master and such. That worked just fine.
Gen III is where I felt like pokemon had a slight... genre shift. It became less of a feel of just an adventure and more of a... party feel to it. I guess that was slightly owed to the more... balloon-y graphics and the fanfare music. Oh, but that's another thing: Gen III probably had my favorite overall collection of music, even if it contributed to what I believe to be the genre shift. Another noteworthy thing about Gen III is that I indulged in many of its spinoffs: Mystery Dungeon, Pokemon Ranger, and Pokemon Colloseum. Each of them wasn't quite like the core games, but I enjoyed them for what they were. Especially Colloseum--my God it was so interesting playing with such a usually light concept (like Pokemon) in such a dark setting (like Orre).
Gen IV... I didn't hate it, but I wasn't particularly impressed either. It had some good pokemon and... that's about it. It had nothing special and the battle system was REALLY, REALLY SLOW. The one redeeming quality it had was HG and SS, but I basically considered that Gen II rising from the grave, so points mostly go to Gen II for being reminded of how great those games were.
Gen V was really interesting. I don't know, once again I felt something different emanating from it. I like it for what it's worth, but strangely enough Gen V had a very compelling story--far different to its predecessors. I really like this Gen, for what it's worth.
I guess in the end my preference goes like this:
II > I > V > III > IV
