Strongest hero at level 6?

Seeing as I recently saw a 'strongest hero at level 1' thread, I'd like to know the community's opinion on this; who do you think is the strongest hero at level six (assuming said hero has respectable item and ability builds?

I think this one is absolutely no contest.

Earth Spirit.

A 1600 range Blink. AOE stun. AOE silence. AOE slow. 2000+ AOE magic burst damage. Can pretty much solo an entire team.

Lina or Lion

both have crazy burst that can kill anyone at level 6(bar a few heroes)

and its usually too early for them to have BKB so they are usually good then.

Is this

"A hero whose peak is at 6"

OR

'If everyone is at 6, then who is the strongest'

?

The latter, TheSofa.

Earth Spirit seems like the best candidate, as Hamster mentioned, he is absurdly powerful at that stage with his various crowd controls, crazy damage, and mobility.

Other good contenders:
Axe (Helix is really strong early and Culling's kill threshold at level 1 is very high),
Undying (Strength sapping is big at this stage, and so is tombstone, with Golem, he is a nightmare),
Enchantress (Impetus + 2-3 creeps assisting her makes her super dangerous),
Slardar (Physical damage nuke is big, and so is -10 armor in early game),
Night Stalker (at night) (Crazy MS, very tanky, Void is one of the strongest single target non-ultimate nukes),
Bristleback (Stacks go up fast and Warpath adds a lot in this stage),
Visage (Familiars hit hard, cloak makes it hard to fight him without dots, and chill will suck away your ability to fight back),
Dark Seer (Extremely tanky, and Ion Shell does a lot of DoT damage early in the game too, while it is impossible to run from him).

Bane deserves a special mention here, since he'll have two disables, a pure damage nuke/heal and Fiend's Grip pretty much guaruntees him kills on squishy heroes like Sniper, Crystal Maiden or Enchantress. Seriously, Bane is one of the better early game gankers in the game and any hero with a disable that goes through bkb isn't to be underestimated.

Imba spirit is a good one!

The first one i thought about is Brewmaster. that ult just does so much work, and even out of it he is tanky and has good slows.

When you say Imba spirit you have to give precisions, since all 3 spirits are imba. Kappa.
