You're right that there is no obvious right or wrong, but I don't think it's a matter of background either. For example, I have a similar background and think that the "old" way of doing things is an over-abstracted waste of time. I spent many years doing frontends with CSS, then Less, Sass, and I have used all of the popular methodologies at some point or another. I am very comfortable building things that way, and it would probably be my preference, all things being equal. However, developing with Tailwind is just plain faster than the other methodologies. And it's easier to adjust components in production. When it comes down to it, those are two areas that Tailwind excels in, and high-abstraction CSS methodologies (despite their other merits) do not.
