One opinion believes Chimchar is the better option but states that it, Piplup and Turtwig are all cool and neither one is stronger than the other one however they wouldn't pick Piplup, they would choose Chimchar or Turtwig.
One opinion states that none of them are the best but believes that picking the Grass type will make the game easier.
One opinion states that Turtwig is the best between it, Chimchar and Piplup since once it evolves, it will become a Grass and Ground type which can beat Piplup which is a Water-type and because of its Ground-typing, it can also handle Chimchar since Chimchar is a Fire type and Chimchar being a Fire type doesn't do well against Ground types.
Piplup is stronger, cuter and more loyal than turtwig and chimchar! For example, Piplup, the penguin Pokemon can use water type attacks on chimchar, and ice type moves on turtwig!
If you pick Turtwig, regardless of your character's gender, your rival will have Chimchar and Rowan's assistant will have Piplup. If you pick Chimchar, your rival will have Piplup and Rowan's assistant will have Turtwig. And etc. No changes are caused in the storyline, no matter what you do.
Turtwig Chimchar Piplup
out of piplup, chimchar and tutwig it would be PIPLUP! Piplup ca use water moves on chimchar, and ice moves on turtwig. the second is turtwig and third is chimchar. (I chose piplup and now it's a strong lv 100 Empoleon now!) PS: "Give it a try!"
You get prinplup when piplup evolves. To get piplup you either pick chimchar, turtwig, or piplup.

Turtwig (grass) Chimchar (fire) Piplup (water)
in order from best starter to worse Piplup Turtwig Chimchar
if you choose turtwig as your starter than your opponent will have chimchar if you chose piplup then your opponent will have turtwig and if you chose chimchar than your opponent will have piplup.
You can only get one of these starters in Pokemon platinum: piplup, chimchar, or turtwig. In my opinion it is best to get piplup for type advantage. Example: if you get chimchar your friend (on the game) will get piplup, and chimchar is fire so piplup will win because it is water. Same thing with turtwig, he will get chimchar and grass is weak against fire. But with piplup, piplups only weakness is electricity and niether chimchar, or turtwig is electricity so piplup is your best bet.There is a cheat to get all three of them but I don't know it so the only way you can get piplup if you already have chimchar is to trade with someone who has piplup.
