O(n) companies tend to have more experienced founders and engineers in my experience. This is partly why they have "nice deadlines, clear SoW" and "understand their customers" enough to have PMF. The strength of their talent, experience and job networks often greatly outweighs the cash incentives, allowing them to hire top candidates. They do not just hire "to fit a job description" because, since money was tighter, they are super conservative about hiring, have always done the job they are hiring for themselves for a long time, and know exactly what they need. It is the O(n^2) companies that hire for job descriptions that fit the positions the VCs tell them they need. I think your experiential datapoints may be too sparse.
