I'm wondering what, in your opinion, is the best Pokémon game. Specifically not your favourite, but the one you would show to a complete newcomer to show what the mainline series is at its best.

My personal thought would be either Emerald or HG/SS, but I admittedly haven't kept up with the series so much after Black and White 1, which I disliked the designs for and found too slow and hand-holdy.
