CRCB (Canada Recovery Caregiving Benefit) and ODSP

Hi, is there any info out there on how clawbacks from CRCB works? I have read CRB is $ for $ as it is treated as EI. I, as a spouse of someone on ODSP, qualify for CRCB and wonder if that would be a better option since CRB basically just be a minor improvement on ODSP on its own.
