Pokemon's metagame has gone through a lot of changes over the years with all the new mons, types, moves, and gimmicks that have come and gone. Which one is your favorite? And if you feel so inclined, why?

For me, I think that gen 6 might take the cake. The PSS was extremely convenient, the introduction of megas was exciting, and I felt like the vibes were generally good all-around. I also have a pretty big soft-spot for gen 4 and 5.
