All three of these suits are of similar SFI-1 fire retardant cotton (FRC) construction. The K1 Challenger is a step up in comfort from the other two though as it has a 360 degree separated shoulder gusset:
This separated shoulder gusset allows your arms to move independently of the rest of the suit without tugging on other areas of your body making the Challenger suit a more comfortable suit for longer race sessions.

What is the sizing chart for the K1 Challenger Suit?
The safest suit for maximum fire protection is a loose fitting one.
A suit's fire protection capability is directly related to the fit of the garment. A properly fitted racing suit will have small air gaps in between the body and the garment. A suit worn too tightly will compress these air gaps- allowing heat to reach the skin faster.
