Hank Scorpio vs Duffman

Hi,

just looking for a few opinions on which character or not at all to buy.
I play freemium, so every donut is earned hard :-)

I am at 171 donuts at the moment.
Should I get the Mastermind Bundle 160-40 donuts or Duff Brewery fpr 190-60


Mastermind Bundle seems like a nice deal, but I don't really like the character; but it helps with the event, and maybe some extra dounts in the end.

For Duffman I will need to save a bit more... but could probably get him before he is gone...

Or should I wait and see what comes with part 2 of the event?
