They are NOT the same at all, small variations in the ingredients used and percentages make all the difference. How could you even compare something like Top Fuel and Blue Thunder to Byrons or O'Donnell's? Thats right, you can't cause the latter is in a completely different class. Byrons and OD have always been my favorite, Sidewinder was great too. Eager to try Nitrotane and Maxy's. Never tried BT/Trinity/Rocket Sience/Wildcat.
