For me the thrustmaster wins as you can split the throttle from the flight stick and it was just enough cable to sit either sided of the keyboard. Could not get to grips with them when the 2 sticks were attached as this felt very restrictive in movement.
I fully agree with this. I can't emphasise enough how important it is to have a separate stick/throttle to add the immersion of the game.
I had a Saitec/Madcatz Fly 5 stick which had a built in throttle. However it felt too confined having the throttle right next to the stick. It was a nice stick, but I ended up selling it.
The ability to separate the throttle and stick (which the Thrustmaster HOTAS X lets you do) is a major plus.
