Won what? Speed, bump smoothness, traction? So many variables. Rider weight, terrain. tire psi and so on. My summer fat bike tires are 4" and usually 7-12 psi. My 3 " tires on the Krampus are 10-18 psi. Add in 16. 17.5 and 29er rimes too. Try this, do some demos, decide for your self on how you ride your terrain. My fatty in the summer on less tech trails wins for the fun factor.
