FUAC's offer was all cash. The Onion offered less cash, but offered other incentives (AIUI, a share of whatever revenue they make from Infowars in the future). Saying that The Onion's bid was lower requires you to put a dollar value on those other incentives. The fact that the two creditors (read: victims' families) that would benefit from those incentives were willing to sacrifice some of the debt they were owed so they could benefit from those incentives suggests that at least _they_ think those incentives were worth more than the cash upfront, and the amount of debt they were willing to sacrifice gives you an implicit baseline for that dollar value.
Given the site we're on: it's like saying that an offer with a lower base salary but higher equity is automatically a worse offer than a bigger salary with no stock.
