The most important difference between 1 and 2 is, IMO, the width limiter. You can actually read the source yourself, it’s extremely simple hand-written HTML & (inline) CSS. max-width:650px; stops you needing to crane your head. It also has slightly lower contrast, which I’m told is supposedly better for the eyes according to some studies, but personally I don’t really like as much, which is why “Best” is my favourite, since it has a little button to toggle between light mode and dark mode, or between lower and maximum contrast.
