Same here. I can’t really tell if it’s bias because I am very comfortable with RPN, but another of the benefits of RPN is that it seems much easier to build up

Same here. I can’t really tell if it’s bias because I am very comfortable with RPN, but another of the benefits of RPN is that it seems much easier to build up a complex computation on the fly without having to backtrack and add parentheses, which on most calculators means you have to start over. With an infix calculator, I have to plan the whole thing out precisely before I even begin entering it, whereas RPN feels like a “streaming” translation that is very easy.
