There really is none, at least not that is comparable. InDesign is perhaps the one product where Adobe really shines.
Aldus PageMaker and Quark XPress were worthy predecessors; I used both back in the day, but Adobe bought PageMaker and discontinued it. As for Quark, not sure what happened to them but they're not around anymore.
I used Quark XPress, and it really felt like it had a monopoly on the professional market in the UK at the time. It didn't really innovate, it was slow and clunky. Then InDesign came along and it was a breath of fresh air.
Took many years for the transition to happen, but a lot of people in my circle wanted to see the back of Quark.
When I worked in desktop publishing (35 years ago, sigh) we used Ready, Set, Go extensively. Certainly seemed like a more intuitive UI than what little I've seen of Quark, at least.
