Extreme Flight sells the best 3D planes out there, and so the 52” slick will fly amazing. OMP Hobby hasn’t been our there as long so I’m not sure what the quality and flying characteristics are, but what I’ve seen from their bighorn, they are good planes. It also depends on what type of 3D flying you plan to do. The Slick will excel at XA or Jase Dussia type of flying, whereas the SBach is more of a Sport/3D hybrid and will be more geared toward IMAC flying and low-n-slow 3D stuff, not really XA.
