I presume the capacitor incident was to blame? If that's all, then I stand by my statement that you're making it out as more than it is. If capacitors were the reason, and it was only for the high end PSUs, then it's very possible and much more likely that 60% was a real number, but then again, as I'm saying, that is not an actual reflection of either Antec's failure rate nor their quality level.
I wouldn't consider bad capacitors entirely Antec's fault, at least not to the point to where you can say outright that their PSUs are of bad quality and "they suck" like you seem to. As you know, capacitors aren't something that they manufacture themself. They get them in through a supplier, and if those are failing, it's said suppliers fault. Don't blame Antec simply for a rash of failures happening. Many companies went through that due to capacitors being poor, including ASUS, Gigabyte, Dell, HP, Intel, Foxconn, and even GPUs and televisions. By time anyone found out, it was already too late/already happened.
Seriously, people think that Seasonic is a cheap brand? That Thermaltake is the second best? That Antec is all bad? That Hiper is really good? Where are you guys getting your information from? Do read some reviews from the people who know what they're talking about rather than biased claims of "this brand is good and that brand is bad".
