Well, from a marketing standpoint SoJ may have had the edge (in your opinion, as I've said regardless of whether they offended fanboys or not, their American ad campaign was quite successful overall), but their ideas about hardware and software were downright stupid in many instances. They ignored the success of American-developed first party games like Comix Zone and Kid Chameleon, they ignored the suggestions from SoA about making the Saturn backward compatible, they rushed the DC to launch in Japan and lost a ton of money thanks to Sonic Adventure being the only game anyone wanted in their JP launch line-up, and really that's just the tip of the iceberg. I think history has shown SoJ bears the most blame for Sega's failure as a console manufacturer.
