Where you're talking about the Atari joysticks, you have a pic of the O2 (you also have "Atari:" in the upper-right corner of the pic).
As far as "worst" controllers go, there's a few I'd consider far worse than the Jag's (which was too big for small kids, but otherwise worked well), such as the 16-button Intellivision and 19-button (!) 5200 controllers (which did not work well). The Colecovision joysticks weren't well-designed either (and the Super Action controller had 16 buttons and an analog wheel! The standard Jag controller had 15. Your article shows a pic of the Jag Pro controller, which had to be bought separately).
Overall nice article
