I can only comment on three sticks I have used.
Saitek X-52 was okay, but needed a spring fix on the stick to help make it feel tighter, the initial batch had an awful Deadzone problem which was improved but not fixed in later versions.
Saitek X-52 Pro. Much better, the throttle and SST Software were fantastic and the stick was very good. The Deadzone was fixed as-was the spring tension and I used it for a good two-years without problems.
Thrustmaster Cougar Hotas with Gimbals and Hall Sensor mods. OMG! Best investment I ever made. The stick is rock solid, very heavy so no movement off desk, the programming software is excellent and there are so-many profiles and the stick has a feel that it will never fall apart, very, very sturdy.
I also have the Simped Rudder pedals and these too are outstanding.
If you have the money and you mainly fly propeller aircraft (as I understand the warthog is better for jets) this modded stick is just awesome!
So Modded Cougar and Simpeds will last you until BoB:SoW:1946 comes out at-least!
