Frost Titan or Shipbreaker Kraken?

[Prospero101]

Hi, folks! I'm brewing up a Dimir control deck with a milling subtheme to start playing Modern with a few of my friends. I have basically everything filled except my six-drop bomb. But I just can't decide between Frost Titan and Shipbreaker Kraken. I've compared them, but I could use some input. What do you guys think?

FROST TITAN
Pros:
Solid 6/6 body
Its effect is immediate and most assuredly happens at least once, barring counterspells

Cons:
People freak out when they see a Titan, so it tends to die pretty quickly
I don't have a foily version

SHIPBREAKER KRAKEN
Pros:
Solid 6/6 body
Its effect is more potent
I got the foily promo version at the prerelease

Cons:
Its effect is costly and depends on Monstrous
Monsters also tend to die pretty quickly

What do you guys think? Bear in mind that the decision is between these two because I have both of them. I'm not going to go buy a Grave Titan or a Silent-Blade Oni or something.

I'd go with Titan, myself, but it's a close call.

Frost Titan because it is harder to remove as removal cost 2 more

I'd say Frost Titan easily. IT's just a lot harder for your opponent to deal with effectively.

That is a fair point. I'd actually forgotten that he had that "Counter it unless opponent pays 2" ability.
