Display and User Interface Comparison
The ProForm 905 CST has a 5″ backlit iFit display and the ProForm Performance 600i has a 10″ full color capacitive touch display. The Performance 600i has a touchscreen which is great while the 905 CST has buttons for controlling the treadmill, so browsing the menus is not as easy as the Performance 600i. We think the bigger display size of the Performance 600i is a plus. 
Built in Programs
The Performance 600i has 20 more programs, 50 vs 30. Both treadmills are iFit Coach Compatible so you can get many different workout options.
Bottom Line
We gave the ProForm 905 CST a rating of 80 over 100 while we gave 75 for the Performance 600i because, the 905 CST has a stronger motor, more user weight capacity, and a good price for the features you get. Also larger belt size of the 905 CST makes it a superior option for faster workouts.
