I am biased ( a former coworker was an Uncle Bob fan, and was bent on doing everything by the book, with layers of abstraction, patterns, hexagonal architecture, lots of unit tests, no cutting corners, even as we did not know what exactly we want to build and needed an MVP ASAP) but I'll just say this: Ousterhout wrote TCL - widely considered one of the best C codebases - besides being a professor at Standford and having other software achievements under their belt, while Robert Martin is more like a software technology evangelist. The former good at actual deliverables the latter good at selling.
Also Ousterhout's book on design is very easy to read and I guess I liked it because I mostly just nodded in approval while reading and there were very few things that made me stop.
