Fwiw, most PRs are way subpar in quality compared to H1Bs. There is a horrible echochamber here where people who scored CLB9 or even lower assume they are somehow better - most of them have never worked in the US or with H1Bs. As long as CRS isn't rewarding for exceptional pays, outstanding academics, etc - we know the bar is extremely low.America forces you to get a Masters for STEM H1B (bachelors H1Bs are very rare) while in Canada a graduate certificate can be enough to get a PR and many times a bachelors is not required for it (Ontario graduate certificate for example). The bar is lower for a PR. The bar even in a sweat shop is high compared to a Canadian PR. A sweat shop consultant is still an engineer even if he is a bad engineer is what I am trying to say.
I did french ffs to get my PR, it was lame and unskilled - my next plan to land here through C11 pathway. The latter would've been far more respectable. 90% of us here are the former language->PR route folks. We realistically aren't better than a H1B. American culture shapes and challenge these professionals - they collect world class talent, make it compete based on some of the world's highest productivity standards, and helps you grow with uncertainty. There's a reason why comps are way higher in the US, has less to do with "corporations", more to do with the extremely poor labour productivity in Canada.
