Spoke breakage is ALL about the quality of the build, practically nothing to do with the quality of components.
If the spokes go into compression, they will fail. The spoke tension needs to be high enough that they never go into compression.
I am 300+ lbs; build my own wheels for quality and cost. Mine are all 36H or 40H. My favorite rims are Sun CR18, favorite spokes are Wheelsmith SS14, and on some wheels DH13.
As noted about - get wider tires; the widest that will fit in your frame and fork.
