I think you're looking at it all wrong.
It's because you're more interested in harder choreo and that is what BG's mainly do. You want something sharp and precise, fast and hard.
So, I think that GG choreography isn't really your thing because it's not hard enough for you.
BG and GG choreography are completely different.
Although GG choreo tends to be much softer, not all but a lot, it doesn't mean that it's not good.
I have seen some really soft GG choreo but they have been beautiful.
At the end of the day, BG choreo is your preference, because you like to see that type of performance.
I personally think that Oh My Girl's SSFWL has such beautiful choreography!
I honestly prefer GG choreography than BG's, however I do appreciate GG doing BG choreography more as well.
