Does anyone have a table comparing fees and charges when redeeming flights on different frequent flyer programs?

When cashing in points to redeem flights, it is often quite alarming how much some carriers slug you in fees and charges. For example, a one way flight in business class from Dubai to London costs 50,000 QF points and about $550 in fees and charges. A one way business class flight from Darwin to Melbourne costs 36,000 QF points plus $94 in fees and charges, which is almost one third the cost of an economy class ticket. Yet when booking the very same Qantas flights using AA points, the fees are a lot less. Has anyone done a table comparing the fees and charges using the most popular frequent flyer programs on the most popular routes?
