You kind of have the worst of both worlds there, because you'll end up.... In my experience, you go with a sole source if you have the exact perfect person. It will be under a certain amount, and you can just go ahead and do it, often for speed and efficiency and under the pressure to just get it done.
Then you have situations in which it has the appearance of an open general bid process, but as seen on the slide earlier, 90% of the time it's already landed with someone. There you've gone through this epic process and ended up with the winning bid that people could have predicted earlier. You have all the worst of that happening.
