To answer your question where the butt joint is not subject to stress and
blended for cosmetic effect the screw and dowel construction are the most
effective. Where the joint is subjected to minimum to stronger stress, as
stated before, "Consider a scarf, finger or lap joint". If you are dealing
with oily wood like teak even two part epoxy will not adhere good you have
to add mechanical devices like screws or equivalent.

to reinforce it with a)screws, b)dowels, or c)biscuits. Anyone have an
opinion as to which of these 3 would add the most strength to the joint?


Butt joints are the weakest. Consider a scarf, finger or lap joint.
