I used to do the reverse; I had something like a million IHG points and I redeemed them for air travel several times. I knew it would take a long time to use them for hotel redemption, I figured I might as well spend them before they get devalued.
I move all my Marriott points to UA and use them for upgrades. I've never really "done the math" as far as $ value. But I almost always get free upgrades to a suite at Marriott and never get a free UA upgrade.
