> I know I’ve personally lever liked the cheap flimsiness of mass market paperbacks
I'm in the opposite boat. Growing up, I mostly had paperbacks, and when I encountered hardcover, I just couldn't fathom why someone would pay so much more for something so obviously inferior. They're a bigger pain to hold. Not convenient to put in a backpack. Take up way more space on the bookshelf. Etc.
There are different grades or constructions of hardcovers. What you're describing is likely a cheap adhesive casebound. At the other end are the lay-flat hardcovers with sewn signatures and a specially constructed flexible spine. Those are a joy to read.
The French are on your side. They love their premium paperback: https://en.wikipedia.org/wiki/Collection_Blanche
Hardbacks also hurt more when you fall asleep reading in bed and drop the book on your face.
Strong +1 from me. Hardcovers look nicer but are a PITA to read from, especially when traveling with them. I almost exclusively buy paperback when I opt for dead-tree books simply because the actual reading experience is nicer.
That said, I usually just stick to my kindle.
