Which scale?

I can't decide what Samurai miniatures scale I like better, either 6mm or 10mm.  I bailed on 15mm years ago due to I think cost and rules I thought I'd use.  As to 28mm, I just don't have any interest in Samurai skirmish.

What do you think?  6mm on left or 10mm on right.  Bases are the same size.

Well, so far from what I've read in the comments and who I've talked with in person, it seems like 6mm is the only choice.  I can certainly give 6mm a go again.  I am definitely not a fan of the plastic weapons breaking on the 10mm minis I have.
