The long ones (that basically spoil the plot in the title itself) are mostly isekai, made to distinguish themselves from each other in the oversaturated isekai light novel/manga market. Probably 90% of all long anime titles are from the isekai genre alone.

Blame Hanako for that slip into insanity 😂

Asobi Asobase OP: What the girls think they are Asobi Asobase ED: What they really are

Anyway, I agree with you. The KonoSuba EDs in general are too underrated. Like hell, everyone remembers the iconic Kimi to mita sekai from the first OP ("fantastic dreamer") and the opening beat from the second OP ("Tomorrow"), but they seem to forget the calm EDs.
