It may appear that way, but remember... year after year, TGLC plays the quantity game very well. They're still the only large coed team to put up 12 stunt groups for their elite stunts (kudos to those 6 female bases); they have two coed and two elite stunt sections; they have a large amount of group standing and running tumbling passes showcasing synchronisation; a pyramid packed with transitions and ending with such a big structure that highlights their use of the floor space.
The more athletes you can get to perform skills at the same time, the "more time" you can get in your routine. i.e. Instead of having a staggered standing tumbling section (e.g. 8 athletes performing three two doubles, followed by another 8 performing two to doubles and lastly 4 performing one to whip doubles.) you have what teams like Orange has (e.g. One giant group pass with 20 athletes performing two to doubles). You can the allocate the "extra" time to put something else in... so their routines may not necessarily look "difficult", but they just have the quantity and execution.
