What 5e subclasses do you think most or least fulfill their intended fantasy?

I have not seen Eldritch Knight in this thread so I am asking, what is the consensus?

Or is it so "blah" it is neither good or bad at fulfilling its stated role?

I think it pretty much does what it says it does, a Fighter with a bit of magic to supplement their fighting, it’s just that a lot of people expect them to be slinging more spells, at which point Bladesinger is probably a better fit as a caster that supplements with fighting.
