The problem is you're comparing the PS3 to consoles with far superior libraries. The Dreamcast and Saturn, while not the successes that Sega would've liked, both have stacks of good games (the Saturn's import selection is especially brilliant) and leave the PS3 in the dust. Furthermore, they are very different from EACH OTHER let alone Sony's machine.
There isn't really a machine coming to mind that I could liken the PS3 to. It's a reliably designed console from a manufacturer fresh off two consecutive generations of utter dominance both software and market-wise, but has a pretty average selection of games and from a developer's perspective, isn't as friendly to work with as its rivals. We could produce an essay's worth of comparison points but imo you can't call a console the "insert name here" of a generation if it can't hold a candle to that console's software selection.
