Probably my most influential blog post in the last 18 years - the one where I got the most number of people to re-examine long-held beliefs about what they thought was true - was the "Full Frame vs. Small Sensor (don't laugh)" post from 2017, where I pitted my 42 megapixel Sony A99 II against the tiny 20 MP RX100 V point-and-shoot.  When enlarged to poster size and scrutinized, nobody could tell which camera took which image.  

Well, guess what?  https://friedmanarchives.blogspot.com/2023/07/full-frame-vs-smartphone-dont-laugh.html

Prepare to be either impressed or annoyed!!

Sincerely, Gary :-)
