I can see Sampras attacking Fed's 2nd serve more, putting him under pressure. I think he could make Fed crack just a bit to pull off the win (similar to the margin you suggest).
Federer has the best tiebreak win rate ever IIRC. I'd favor him in those situations. It might just depend on the court, although IMO the difference between Federer and Sampras on faster surfaces is slimmer than the advantage Federer holds on clay or slow hardcourts. Overall I think peak Federer has the edge.
