Best: by far playoff moments, I've pulled many amethysts, current and playoffs, even diamond LMA. Although most of the content is worthless by now.
MVP packs: no diamonds, but quite a few purple MVPs.
DPOY packs: lots of gold DPOYs plus current AD and DPOY Hakeem.

Utter trash for me were: TBT, Moments, Dynamics (yup they still exist) and All Star packs.

I can't say anything about regular packs, I haven't opened any since the 1st month of release.
