Considering that C-3PO waas verbally very competent, but somewhat clumsy, I agree. Even the "old" Boston Dynamic robots are more agile than 3PO.

Hmm, perhaps that clumsiness was a programmed affect designed to disarm those he interacted with. After all, as a translator and master of protocol, outshining his master in any way would be quite against his programming.

I think you're onto something, given that IG assassin droids exist in-universe and are anything but clumsy.
