I am with The Sword, in general a flat number is better for speed and ease at the table, with some situational exceptions.
Adding a d4 to a d20 attack roll requires grabbing up two different types of die at the table and adding two dice plus a modifier in the middle of what should be a fast paced combat. The more people at the table the more this is a problem.
Adding a die after the fact as an action die/hero point is a great mechanic that I endorse for a puply/cinematic hero feel, but so would a mechanic to spend the hero point to flat out succeed on that roll.
Advantage is a simple fast mechanic at the table, I like it a lot and more than tons of situational flat numbers. Two dice of the same type and use the better one when there are no other dice to track is quick and easy and is great for replacing tons of other situational modifiers that slow things down. 4e's flat +2 tactical advantage was great and easy to apply broadly too.
