4th Gen Pearl, Diamond or Platinum?

Hey guys, I take pride in having played through every Pokemon generation, but for some reason, gen 4 is very hazy to me (so is gen 5 but I haven't actually finished it yet lol)

So I want to go back and play, my question is is Platinum the perfect mesh of the two? Is there something better about playing one of the main installments? Thanks in advance everyone

To be honest I played Diamond to its death, literally my card died. After that I played Platinum once and noticed significant improvements compared to the D/P series. Just because of nostalgia I'd go for Diamond, but Platinum is definitely higher up there in terms of being more polished and more content.

In my opinion, Platinum is superior to Diamond and Pearl, it takes what was so good about the originals and makes it even better whilst fixing all the faults they had. Mechanically, Platinum is so much better, as Angie mentioned it fixed the awful surfing but also sorted out the horrendously slow battle engine. I felt like Sinnoh is more complete in Platinum as well, and the Distortion World was pretty cool too.

I played through Pokemon pearl first I spent about 300+ hours with it
And after Pokemon
platinum came out i bought it instantly and played it for about 3 month before restarting my save And after that i played through it 3 more times So i gotta say i loved Pokemon platinum
more than Pokemon pearl A lot of more cool stuff were added Older areas were built bigger and better And the battle cafe was added which was my favorite building in the whole 4th gen

Platinum is most definitely the best of the trinity. Platinum fixed many issues that were existent in D/P. In terms of story, Platinum also digs deeper into the creation trio backstory. If you're looking to play a game, I'd go with Platinum. Overall, third titles in a series are better then their predecessors.

Diamond has my fave version mascot of the three, but for reasons the others have already stated, Platinum is superior to Diamond and Pearl in literally every way possible.
