Scrivener Is a good software I like and use it in my writings of papers and books

If the ability to write longer texts outweighs the need for an agile

A dark horse option, not dissimilar to Scrivener, is Atomic Scribbler:

It isn't robustly updated, but you can download a trial copy to see how
it works for you.
