I bought both of those sets today. Rasputin, the castle was 50 bucks. Luckily I had a 20% off coupon. The battering ram set is exactly the same as the falcon knight set. This blue double axe heraldry has become my favorite. I'm in the process of creating a new army of these. Right now I'm up to 32 blue and 45 yellow double axe knights. I will post pics when I'm done.
On a side note, the black helmet on the leader on the battering ram set looks like a new color. Also the helmets in the castle set are silver. I have only seen the bucket and flared helmet in black. The double axe shield has a dark border. The double axe fig in the knights carrying case has a silver border.
