Gongora is far from being the worst. He wanted to stay in the world to become a God and stay immortal. If you go under his mansion he actually explains his entire reasoning/logic as to why he became the "bad guy". His reasons were logical and he was pretty badass, just not as bad ass as many other villians these days.
Nene was pretty lame from what I remember but that's just me. I can't honestly remember a real bad boss from a JRPG outside of him and maybe the Enchanted Arms final boss/biatch.
It's just that simple.
