I guess I would rate it as "B" overall. Mostly off loaded guys that would have been gone after the season ended anyway. Best to get as much as possible for them.
Hard to rate this in a vacuum, though. The trade deadline sell-off was a decent first step, but there is so much work to be done to make the Mets a viable team going forward. So much depends upon how the team utilizes the money coming off the books and prospects attained to fill many glaring needs (bullpen, starting pitching, second base, first base, & dependable RH bat with power) in order to be competitive in 2027 and beyond.
