You mention the HP Envy and HP Spectre lineup, I’m not certain how they compare individually to the Framework laptop, or the size of laptop you tested - it’s possible the 15" and 13" models of each of those two have different key spacing.
However, if you’ve tested an HP Elitebook 840 (their 14" model) the Framework laptop’s keyboard is almost exactly the same overall size (clearance betwen keys), with what is in my opinion superior individual key feel. I may be wrong, but the latter observation feels like it’s due to the Framework’s keyboard having keycaps which stick a little bit further out of the frame than the HP’s - this means that as you touch type, your fingers can much more readily tell when they’re in a position where they can press down on the keys. It feels more assured typing on that keyboard than on the Elitebook. With that I’d hand the “small hands typing test” (no pun intended) win to the Framework over the HP, given the improved tactile feedback.
I have above average hand span for a guy, but my girlfriend also has tiny digits, and she had zero complaints typing on the keyboard. That being said, she’s also accustomed to typing on a full size mechanical keyboard for home computing, so take our word with a grain of salt.
