I found Seasons consistently more challenging to transverse than Ages. Ages felt very straightforward to me what to do in the overworld. I ran into one small problem late because my short-term memory went out on me, but that was it.
And it has bosses that can actually put a fight, Ages doesn't. It also has the better items, even if its items start weaker.
Seasons has stronger subbosses than the final boss of Ages.
