Which Sunkern to evolve?

I have 3 Sunkerns, and I want to train one in order to evolve it to Sunflora though I don’t know which one. The reason I’m having trouble is, because they each have a different ability (Chlorophyll, Solar Power, and Early Bird). Which should be the best to evolve.

I wanted to do a double battle with Ninetales (that has drought) and a Sunflora that would help it out, but I don’t really know.

Suggestions and help please.

Chlorophyll-Boosts the Pokémon’s Speed in sunshine.That Is Good In Double Battle With Ninetails With The AbilityDrought.

Solar Power-In sunshine, Solar Power raises the Special Attack stat 1.5×, but lowers the user’s HP by 1/8 of its maximum HP at the end of each turn.Which Also Can Be Good In Double Battles With A Ninetails With The AbilityDrought.Its Up To You But My Opinion Would Be To Evolve The One With The Ability Chlorophyll.

Early Bird-The Pokémon awakens quickly from sleep.Well Isn’t really benefiting from the sun like the other two abilities do.So I really wouldn’t consider this ability unless your battling an Opponent with Sleeping Moves.

Well, if used in a sun team, the Sunkern withChlorophyllwould be the best one to evolve.

In a double battle, whileSolar Poweris useful as well, it decreases its Hp yet increases its SAtk.

AndEarly Birdis good with a rest combo, which it can learn, is another option. It can also work.

So all three abilities are good, but in a Sun Team, Chlorophyll, which raises its Spd, is the better ability.
