Which is better dialga or palkia?

As a Pokémon expert, I can tell you that the comparison between Dialga and Palkia often comes down to personal preference and the specific context in which they are being used, such as in a game, a battle, or simply as a favorite character. Both are powerful Legendary Pokémon with unique attributes and abilities.

Dialga is a Steel/Dragon type Pokémon known as the "Temporal Tower" and has the ability to control time. It can be a formidable opponent in battles due to its high Special Attack and Special Defense stats, as well as its access to powerful moves like Draco Meteor and Flash Cannon.

Palkia, on the other hand, is a Water/Dragon type and is known as the "Spatial Tower." It has the ability to distort space and is often favored for its high Special Attack stat and access to moves like Hydro Pump and Spacial Rend.

In terms of stats, Dialga has a higher Defense and Special Defense, making it a bit more durable, while Palkia has a slightly higher Special Attack, making it a more potent special attacker.

Ultimately, the better choice between Dialga and Palkia depends on your strategy and what you value in a Pokémon. If you prefer a more defensive playstyle with a strong special defense, Dialga might be the better choice. If you want a high-special-attack powerhouse, Palkia could be the one for you.

Based on typing, Dialga has the advantage because it is a Dragon and Steel-type. Palkia is a Water and Dragon-type (don't ask why). Dragon-types are weak to themselves but Steel resists Dragon. So damage from Spacial Rend would be neutral.
