no, twine is miserable, I say that as someone who frequently uses both twine, renpy sdk, and unity unpackers to reverse engineer games. Everything is cumbersome. If anything, without images, renpy is the easiest of the 3 since no innate formating is needed; you can just write stuff like:
Python:
alice "Hey, did you want me to come over later?"
peter "My mom's still here until 6"
"Several hours later....."
then go back later in the future and add images like
Python:
scene alice_peter_phone_1
alice "Hey, did you want me to come over later?"
scene alice_peter_phone_2
peter "My mom's still here until 6"
scene living_room_1
"Several hours later....."
imo the only thing twine is better at is when you have extremely complex branching stories, which almost no avns take advantage of, I'm talking plot forks upon forks upon forks, then it's easier to visualize the spiderweb.
I get that looking at blank renpy pages would be kind of weird, but for a pure story it'd be easy enough to add a background image to the text so it's not boring black, and the same would be the case for html.
