Do you need the gift cards soon enough or want them bad enough to pay $95 to get them?
You may have other UR's to cash in - I don't know. But looking at the math - 75000 UR's = $750 x 1.25 = $937.50 cashed in. Subtract the $95 fee from this and you have a profit of $937.50 -$95 = $842.50. $842.50 - $750 = a $92.50 extra profit after the $95 fee.
@SouthFayetteFan would then take this down to a % but I'm stopping here.
For that, I would keep them, but my use for UR's is not gift cards. I transfer to Hyatt where I get about 2 and 1/2 cents per point value (this varies based on the redemption).
Now, in my case MR's can become gift cards. But many wince at that as MRs are more valuable for fancy flights.
So the point is it is different for everyone. Many would do this. You started out with $750 and end up with $842.50 total so it's not a bad deal. Depends on what you want.
Editing to add: You may be able to cash out before the annual fee comes due, depending on how long it takes to spend for your MSR - mine always look daunting and then they are finished asap. Chase drops the UR's fairly quickly also.
