I'm not sure the OP asks the correct question. I don't think any of those managers can attract bigger names than the other two because of the position the club finds itself in, though perhaps Martinez is at a disadvantage because no one in Europe knows who he is (outside perhaps some people in Spain).
So the question has to be "which manager can get us into or near the Champions' League with the squad we have?" "Which manager can find the key signings that will make the Liverpool engine run smoothly, something that had stuttered along for the last 3 season?"
I personally think any of those managers could do the job provided the correct structure is in place around them, because this Liverpool squad is young and mainly needs direction. We can play 4-4-2, we can play AVB's fluid 4-3-3 system (as highlighted in a different thread), and because of that flexibility and our depth in defence we could play Martinez's 3-4-3. To play 4-2-3-1 would require work (as demonstrated by Dalglish's continual failure with the system this season), but I'm sure that Benitez could find the missing element to make it tick (assuming it's more than just playing Suarez on the right and letting Gerrard drift to the right behind him).
But I wouldn't want any of these managers to bring players from their former clubs with them. I really don't think that is a successful method. No to Wigan, Porto, Inter Milan players! I want them to find fresh blood to grow with this squad - and that will largely fall to the DoF anyway.
