They have fewer moving parts, thus they are easier to build. But their limited range of motion might hamper their efficiency and speed.

I don't really understand your definition of a "dynamic arm," but if you mean a jointed arm then I think you have it all wrong. A jointed arm would be less complex and would give you plenty of flexibility for scoring.
