Ideally you want both. “Trust” is a bit qualitative and includes a lot of factors outside the voting system itself. Just because a voting system is “simple” doesn’t mean people trust it (e.g. Trump voting shenanigans). Obviously just because there are bad actors which can make trust impossible, doesn’t mean you should give up but it is a separate axis to the voting system itself. On the other hand, “verifiability” is a more useful property on a larger scale. You may trust your local government but do you trust local government in all other districts? What if, with sufficient knowledge you could prove that their voting was right or wrong? I think that also seems like a useful property.
