Meirs; tosfos asks kushyos in the form of contradictions on literally every daf of gemara; it’s not a chisaron, it’s the foundation of the search for true understanding of all aspects of torah shebaal peh, including the words of the holy rishonim. A “quick” look at the meforshim is no different than spending 10 minutes on an amud and “quickly” learning up a complicated tosfos. It just doesn’t work.
Is the ohr somayach or rav chaim al horambam a “quick” read?
And yes, the cases in which the rambam contradicts either himself or shas are copious; that’s because he’s not a book to be read, but rather part of the continuum of torah itself.
There’s a famous vort from rav shach about why there are hava aminas in gemara. קודשא בריך הוא איסתכל באורייתא וברא עלמא “hashem looked into the Torah and created the world”, since in the world, hashem was בורא עולמות ומחריבן, he created and destroyed worlds before our own was made, that corresponds to hava amina and maskana. I was mosif on this vort that that’s why there are contradictions; the same way in this world, we see din and chessed, good things and “bad”, but we know that all of it is from hashem and that it’s no contradiction, so too in torah, there are contradictions everywhere, but it’s all really harmonious if we put in the effort to understand it
