I have found some numbers from AMSilk's patent application WO2014037453A1 published March last year: https://www.google.com/patents/WO2014037453A1?cl=en
This patent shows improved numbers from their previous patent concerning fiber production.

This is compared to KBLB's PNAS numbers published in 2011: http://www.pnas.org/content/109/3/923.long

The strength comparisons of the fibers are:
AMSilk: 206.8 to 366 Mpa
KBLB: 281.9 to 338.4 Mpa.
KBLB’s fibers are slightly stronger on average.

The toughness comparisons of the fibers are:
AMSilk: 97.4 to 254 (MJ/m^3)
KBLB: 68.9 to 77.2(MJ/m^3)
AMSilk’s fibers are significantly tougher.

The Young’s Modulus comparisons of the fibers are:
AMSilk: 1400 to 4200 Mpa
KBLB: 4860.9 to 5498.1 Mpa
This means KBLB’s fibers are more rigid.

KBLB has had 2 more years to improve their fibers since the publishing of the information here and Kim has stated that the Monster Silk being used is better than the PNAS strains, so I would hope that they have surpassed these numbers posted by now with their newer strains. I would also expect that Big Red will far surpass these numbers, all likely at a significantly reduced cost.
