>>6288227>>6288228These guys have it right. The Nendoroid Sonic is the best Sonic figure overall, but the Resaurus Sonic Adventure line was the best overall for having a decent variety of figures that had solid sculpts and moderate articulation.
The Jazwares line had the most character variety of any line of Sonic figures by far, but the scale was tiny and the QC was pretty questionable.
Personally I'd kill for a Sonic and/or Crash line of figures from NECA or something, but it's probably not in the cards.
