The orange are tactile switches so they do have a different feel than their green clicky switches. Generally, you'll be slamming the key all the way down coming from a 'clicky' switch, and that can fatigue your hands. Unless that's the way you're doing it now, then your hands will feel relieved from not having to push past the 'click'. And if so, you may want to look into their yellow switches that are fully linear.
The Corsair K63 uses Cherry reds which are like the yellows--fully linear. Coming from a clicky switch you will most definitely only stop pressing the key when it stops moving. Again, this may be good or bad depending on how you type.
The Logitech GPro is an interesting board. I hadn't heard about it before and was assuming it would be using their g-romer switches. But instead it seems like Logitech is using Kalih Cherry equivalents in their GPro line.
Even though a switch is quiet, the overall sound of a linear switch hitting the plate it's mounted to can be more noisy than a clicking switch. To be honest, the cheapest way to solve this is to simply pull out a cheap rubber dome keyboard when you have to type while someone is sleeping and keep the good stuff for when you're able to work like normal.
