How come such a big number of people seem to think that Vader as he appeared in EPIII is stronger than suit Vader?
If anyones bothers to read some of the books or even on wookiepedia it's very clear that suit Vader is >alot< stronger than Anakin/Vader in EPIII.
Not entirely, for example, Vader couldn't use force lightning because of his suit, and because he was mostly mechanical, it severely limited his movement. In addition, he had lost a lot of his speed and agility.
The books suggest that this is one of the reasons the Emperor was looking for Luke to replace Vader.
