[Star Wars] By logic, shouldn't droids be superior to clones?

Droids are basically walking computers are they not? Why didn't the separatists just invest money on creating an algorithm that allows droids to only take head shots with near %100 efficiency?

There are some droids capable of such precision; assassin droids for example have been known to take out Jedi.

But they're expensive, and the Seperatists needed an army, not an assassin. They needed millions of droids, and (given the nature of the Trade Federation) they found the cheapest way to their goal.

Keep in mind, that their plan was to overpower Naboo, and subsequently the Republic, by sheer numbers. They didn't think their weak and flimsy Battle Droids would be opposed by anything more than local security forces and the occasional Jedi. The Republic had no army that they knew of, so when the Grand Army of the Republic literally appeared out of nowhere on their doorstep, they started to invest in more capable machines.
