[Star Wars] How is it that General Grievous had such a mobile and functional armor for his sustenance, yet Vader had a bulky, inconvenient one?

From what I recall, Grievous only had his head and heart as functioning organs, yet his armor allowed him to best multiple Jedi and even throw off Obi Wan for a while. Those 4 handed arms, the sheer flexibility of his droid body made him almost equal (if not better) then some Jedi who are trained in the force.

Why then was Vader given such a hulking heavy armor? Surely injuries like Vader's weren't as bad as Grievous'? Plus wasn't Vader supposed to carry out searching and killing other Jedi? How did Palpatine expect him to do that? I mean, yeah Vader proves us that he doesn't NEED a body like Grievous', but still, why choose to limit yourself when you can be a faster, more efficient killer in the battlefield?

More weird is the fact that Vader himself never tries to upgrade his suit. Doesn't he remember from his clone war days about the droids and other cool tech that can benefit him? Hell he was a mechanic/engineer building pod racers and droids as a kid, doesn't he ever think "gee, maybe I should get a better armor"?

Vader was strong and durable, grievous was fast and agile. vader was a tank, grievous was a assasin. In the comics, vader meets a guy that has the same sort of cybernetics as grievous, and he easily beats him. sure, vader cant run fast, but he doesnt need too. he is slow, but unstoppable and unkillable.
