To be fair, R2 and C-3P0 are high-end utility and protocol droids respectively, so it's makes that they're sentient because they're intended to be long-lasting machines and provide their masters with some form of company. But battle droids are by virtue of their very name intended to be 100% disposable. Their sole purpose for existing is to destroy and be destroyed. So it doesn't really make sense why you would give them any real form of higher intelligence, especially emotional intelligence which might cause them to not pull the trigger on an infant or walk straight through a minefield like a Soviet penal battalion as their Trade Federation masters command.

The first two films actually did this right for the most part, but TCW and Revenge of the Sith to a lesser extent fucked it up.
