What Pokemon game should I play next?

My favorite Pokemon games are Soul Silver and Heart Gold followed by Fire Red and Leaf Green. I played through Sword & Shield and found it to be pretty mediocre. I tried and liked the new features of Pokemon Legends Arceus at first but then it got old and repetitive quick so I never finished it.

The reason SoulSilver and Heart Gold are my favorite is due to the older animation / art style. The vastness of the map, and the story. Based on that information which Pokemon game do you all think I should play next ?

Should I go for Gen 3 and play Emerald or one of the DS games like Pearl ? Or are the 3DS games (I forgot their names) where it's at!?

I will most likely emulate the games so I'm open to trying any Pokemon for any console that has an emulator available for it.

Thanks for your suggestions!
