Which of the 20 legions is the best

and why is it White Scars?

Literally any legion but the White Scars.

How can you say that?

Most forgettable legion is Iron Hands.

Secondly:
>Cool with psykers, but know when to moderate warp usage
>Cool bikes and need for speed, even on their ships
>Lightning assault and mobile
>Mongols in SPACE

I don't know a lot about them but what I do know makes them seem pretty cool

Also adding space wolves.

>uncultured barbarians.

There are 18 Legions.

yeah, we know. 18 named legions, 2 forgotten ones

2nd legion is best legion

literally who?
