You're also forgetting about clawbacks of preferential transfers that happened less than 90 days before bankruptcy. 11 U.S.C. 547.
There is an extensive comparison of the two processes in [1]. Specifically:
> the Bankruptcy Code provides trustees the authority to avoid, that is, claw-back or reverse, certain transfers (subject to certain limitations52) made by debtors
> the FDIC as conservator or receiver may not avoid (i.e., reverse or claw-back) any property transfer pursuant to a qualified financial contract unless the transfer was performed with the "actual intent to hinder, delay, or defraud."
> The Corporation as receiver for any covered financial company may avoid a transfer of an interest of the covered financial company in property [...] that enables the creditor to receive more than the creditor would receive if [...] the covered financial company had been liquidated under chapter 7 of the Bankruptcy Code... (12 U.S.C. 5390(a)(11)(b))
It also calls the 90-day clawback period out explicitly.
