It's actually a pretty good chart. You're probably just complaining because you own a bad/shit tier controller. The comment at the end about economies of scale is real, and it's the reason why Microsoft, Sony and Nintendo controllers are better than ones by dedicated peripheral manufacturers like Logitech and Razer. The awful 360 D-pad is also real. The 360 controller is amazing for games that use the analog sticks (and it's going pretty cheap right now,) but it sucks for retro because the D-pad is unforgivably bad. There's almost no resistance to accidentally hitting a diagonal when you're trying to hold a single direction.
If I was going to complain about the chart, I feel like the Logitech controllers (F310 and F710) are given a bad rap. They're not as good as first-party controllers, but their D-pads are surprisingly good for circular ones. I've heard some people say nice things about them, including that they kind of feel like the ones on the Saturn. I've also heard people praise the Wii U controller, so maybe the guy writing the chart just needed some time to get used to the layout.
In any case, if someone was on the market for a good controller (and not just a decent/passable/usable one) I would recommend ones from that guide.
