H2H: TaylorMade Qi35 vs Qi10 vs Stealth 2 drivers

Firstly, TaylorMade has stepped away from the coloured face and gone with the black carbon face finish. The TaylorMade Qi35 has a Chromium Carbon Crown which is lighter and stronger, allowing for a more aerodynamic shape. 
There are still familiar technologies like the Thru Slot Speed Pocket and Carbon Twist Face which have been improved and refined for performance. But the noticeable difference comes in the head shapes.  
The Qi35 LS has two pin weights with a 13g TAS - which stands for Trajectory Adjustment System. There is two 3g weights at the front which you move around to dial in your ball flight in a low spinning head.   
In the Qi35 core model, you have the best of both worlds, in a larger head shape with two weight ports, one in the back and one in the front. The 13g weight can be placed in the back for more forgiveness and tighter dispersion. If you reverse it you will have faster speeds with lower launch and spin. 
The TaylorMade Qi35 Max is still 10K MOI and has a 34g weight in the back delivering the stability needed, especially on mishits. Across the face, the spin rates are lower across the whole face by about 200rpm and will allow you to get fitted into the perfect setup. 

TaylorMade’s Qi10 marked a milestone with their quest for inertia with the Qi10 Max being their first 10K MOI driver.  
The visual standouts in the Qi10 range is the infinity crown and the blue carbon face. The infinity crown is 97% carbon which looks so clean as it sits flush with the face. This allowed weight to be moved to deliver the best MOI and stability in each model. Between the face and crown sits a white stripe which is there to help you with alignment. This is subtle and looks great behind the ball. The blue carbon twist face doesn't jump out at you like the red in previous generations and delivers impressive forgiveness and distance. 
With the three models we have the Qi10 LS for low spin, Qi10 for distance and forgiveness and the Qi10 Max for maximum forgiveness. 

The TaylorMade Stealth 2 range offered more forgiveness than the previous Stealth, especially for strikes towards the heel. 
The Stealth 2 has more carbon than the previous Stealth model, which has allowed weight to be redistributed in the head for better CG placement and higher MOI. The carbon face was also made redder than the original Stealth and with the Twist Face technology you would see longer and straighter drives, with greater ball speeds. 
The Speed Pocket sits low behind the face to lower the spin on low strikes so great distance and speed are still achieved.  
The three options you have are the Stealth 2 Plus for low spin, Stealth 2 for forgiveness and distance and the Stealth 2 HD which is a draw bias and max forgiving model.
