Did I do the right thing?

The turn before, manicfish had a 4-sided die showing 1 and my 20-sided die showed 7. I chose to take the 4-sided die --

thus giving manicfish an opportunity to take MY 4-sided die with value 1 without having to reroll her 20-sided die.

Did I do the right thing? I COULD have rerolled my 4-sided die with value 1 and had a 3/4 chance she'd have to reroll her 20-sided die -- but I'd give up the chance of rolling high enough to threaten her 20-sided die. Would it have been  worth it?
