Yeah there are always tradeoffs but figured original poster had a basic grasp of their personal risk assessment, and unless you are a celebrity or something I don't think most avg people are going to be targeted by someone with time and drive to do serious data recovery of discarded drives.
Even then if they want critical data from you there are easier ways to get it with less time delay.
Most of the cases I know about where they do serious data recovery of discarded drives are ether gov orgs or white hat researchers.
I think for most individuals worrying much about that is about like worrying about criminals picking locks, when they generally just kick doors in.
For spinning drives I just disassemble them (Torx screws), remove the neodymium magnets and throw the platters away. The magnets I can always find a use for after bending the steel holders flat (refrigerator magnets).
