For the most part, both methods are substantially the same in terms of the amount of time players get and consume. At the end of the move, after the clock is hit, the remaining reserve time will be identical with Bronstein and Simple Delay. The difference is in the time available to complete the current move and becomes apparent when the reserve time runs down close to zero. Because Bronstein does not award the per-move allotment until after the move has been completed, you can run out of time and lose the match before getting the per-move allotment for the current move.
