>>29574274BW2 is an actual sequel, whereas the others are basically just the same as the original games, so in terms of not repeating yourself maybe that?
Platinum is the biggest technical improvement of any 3rd version, so maybe that?
HGSS are possibly my favourite games in the series... so maybe them?
IDK, gen wars are an illusory argument for turbofags anyway, all pokemon games are fundametally the same (and therefore fundamentally enjoyable)
Just pick whichever you think looks the nicest/ has the best pokemon
