So if we ignore Dissidia, Dragon Quest is actually typically more powerful (If not less hax'd and WAY slower) than Final Fantasy. Builders I+II actually retcon DQI-II to scale with III and B2 an outright universal feat. XI is very blatantly multiversal too. Overall the weakest is VII at continental levels, then IX at multi-solar system level at least but likely way higher, while the others are either universal-multiversal by scaling or outright. It's just FF's highs far surpass that. Specifically FFV. But like Mortamor would likely beat Kefka, Corvus probably can beat Kuja, etc. It's just FFV is so beyond the scope of DQ.
