In honesty, the “best” way, in anything in life, is relative.
While for some the “best” way may be to slave over their mishloach manos for days, making something exquisite, for others (think: many mothers with young children), the “best” may mean the simplest mishloach manos to make, leaving them un-frazzled and calm for their brood.
That, to me, is the “best” way to do the mitzvah.
But its all relative, as long as you’ve fulfilled the halachos.
