Fuchs TITAN SINTOFLUID SAE 75W-80 synthetic VS Motul Motylgear 75W-90 Synthetic

which is better ? got that Fuchs for about 10k km and think about replacing it by that Motul. is it worth doing that ? thanks
 
Unless you have an issue with the Fuchs that is currently in there - why change? It's not a normal service item that needs changing every year/12k.
