Both electrons and quarks [as far as we know] are elementary particles (have no internal structure), both are also fermions and hence have half integer spin
I know quite a bit about electrons and quarks:) I guess "structureless" is pretty ambiguous. I took structureless to mean without any internal quantum numbers, and spin is internal in the sense that it is intrinsic. I've never seen an electron called a "structureless" particle, only "fundamental" particle. It would be nice to see some context, I guess.

And 5/2 isn't an allowed spin for fundamental particles:)
