>Emerald
Vastly improved story, slightly improved sprites, battle frontier was a good bonus
>Platinum
Greatly expanded regional Pokédex, improved story, improved dialogue, improved sprites and character designs, added new story elements/arcs, and battle frontier was a nice bonus
The only games of his that you could argue were good right out the gate are BW. XY maybe (better than vanilla RS and DP, at least), but it had tons of room for growth. It’s not just about the battle frontier. If anything, that’s the least important element.

Expanding the regional dex by over 50 additional species and greatly improving the story, dialogue, player character designs, and gym progression are all factors in how DP and Platinum are worlds apart. DP has good bones, but that’s all they are: bones. Barebones. DP feels like an unfinished beta. I don’t put Plat in S and DP in F, but I do tend to place Platinum in A tier and DP in C tier. The things that most affect my personal player experience all changed vastly even if the most fundamental structures underneath did not.

RGB, GS, and BW (and arguably SM) are all better baseline games than RS and DP
