No one really knows, it's nature can be different with each game that's being played. Palkia's faster, but Dialga can learn trick room. Regarding trick room, Palkia can learn earth power as a comeback, which has 90 power and 100 accuracy and is super effective against Dialga, but Dialga knows roar of time, which has 150 power and 90 accuracy. I've tried this before and used it on a Palkia, Giratina, and Arceus. For Palkia, it sucked against roar of time. It was a one hit KO.
Palkia is bad and dialga is good
You can't get Dialga and Palkia in Emerald.
palkia
You can catch Palkia in Pearl and tranfer Dialga to pearl from diamond.
No.

In diamond, you get dialga at spear pillar. In pearl, you'll get palkia at spear pillar. You'll find Giratina at the hidden lake after you beat the elite four.
Beat leader Cyrus of team galactic and then proceed and use the master ball on palkia/dialga (AT THE STONE PILLAR)
After you beat the poke'mon league palkia will be in the spear pillar with dialga
you have to go to hearthome and gain dialga or palkia
dialga, palkia,lucario,heatran,charizard,rayquaza,moltres,and vulpix
first you need beat elite four, then you'll need adamant orb(for dialga) and/or lustrous(grammar?) sphere (for palkia) then go to biggest house in celestic town and talk to old woman, she will talk about dialga and palkia, then go to spear pillar there will be palkia and dialga, luck to catch
I do have the mystery dungeon 2 and you have to beat the game (beat Dialga) to recruit any legendaries. Or, you can beat the game, beat Dialga to get Dialga, then the same for Palkia, but you never get to actually recruite them, I tried.
Dialga you can barely hear palkia's.
