GRX derailleur Clutch drag/friction vs. Sram Orbit fluid

Hello, I am choosing between a new gravel bike with Shimano GRX 810 D vs. Sram Force AXS Wide. After considering pros and cons (shifting, 12 speed etc.), the desition comes to finding what are the differences between the GRX clutch vs the Sram Orbit fluid.

I read that the GRX Clutch produces some drag, is this true? am I going to notice this in any way when riding?

Does the Orbit fluid produce some drag as well? 

which of these two chain solutions could be more appropiate for gravel riding? 

I've ridden both, (the SRAM a fair bit more than the GRX), but in my opinion, neither offer any noticeable drag at all.  TBH, I'm surprised that's what your decision came down to. 

I am not sure if there is a relation between an electronic groupset and possible drag. My main doubt is about the drag on clutch vs. Órbit fluid.
