I like my G940 setup, but I do not have experience with any other HOTAS and rudder. Flying with it for 2 years now.
My G940's stick is very precise and FF fully adjustable to your desire, trim functions on the base of the stick are a god-send. Button layout on the stick itself is good can reach everything with ease, 2 staged trigger does wear a bit over time.
The rudder is good, can make accurate shots during high speed engagements with use of the rudder. The pedals are nice and big and fits my size 48 foot just fine, also has separate brakes when you push the pedal downwards, in the BF109 that makes for good 'on-the-ground' handling.
Now the throttle quadrant, having 8 x 3 ( mode 1, 2 and 3) = 24 different buttons to assign on the base of the quadrant is good, more then I can remember

. The throttle itself is not so good, you can smoothly throttle the plane just fine all the way from 0 to 100% but sometimes there's a few hickups, and then the buttons on the throttle do not work in my case, usually when the throttle is at the 70-100% power range, so I didn't map any important controls to the throttle itself. There's some fixes on the internet, but requires you to de-assemble the quadrant and start messing there, I did some of that but no good results yet.
To relate this to CoD and 1946, I can say that with 45 kills in 22 historical multiplayer missions
vs other squadrons that this stick has served me well
All in all, I think it's a good
complete flight system. I wish it was perfect, but it's not
