I think I like Eden more than Omega because while a lot of the fights are primal reimaginings, they don't feel pointless where as the whole Omega plot kind of felt pointless until after Alphascape. A big old 'prove yourself fighting these references to older games' without really doing much. But part of that has a lot to do with not really being invested in Omega's universal tournament arc thing.
That said I like the FIGHTS in Omega I just really didn't care about the story until the latter half of Alphascape.
In Omega it's nine consecutive fights of fanservice bosses that don't tie into FFXIV's lore in any meaningful way. These bosses could be literally anything and still fit just as well. In Eden, the primal reimaginings have a reason specifically to be there, if slightly contrived, and contribute to the goal of restoring the elements to the Empty in a way that for me at least, was a lot more interesting than just seeing what crazy record from another world Omega's going to throw at us next.
