I doubt that either of them has any noticeable effect on performance. The trunk spoiler is so short and it isn't angled upwards to increase down force. If anything, it might create drag as air trys to flow over the trunk surface. The roof spoiler from Sarona is really more of a visor than a spoiler, but looks great - and the other aftermarket roof spoilers are are also way too tiny to have any effect.
BUT, they doooo look good whislt doing next to nothing! I have both.
