I've used Scrivener more as a drafting tool, since it lacks the powerful grammar checking built into Word. Scrivener helps you keep everything about the novel self-contained. What I used it mostly for was easy organization into scenes and chapters. Much easier to reorganize a novel from Scrivener than Word. You can get similar functionality with Word if you give scenes a heading, but that's an extra step of formatting to fix later... Scrivener also gives you an outline view, an index card view, folders you can organize photos and research into, revisions, ebook exporting, split view, target word counts... the list goes on.
yWriter as mentioned above is a decent Windows-only alternative. It's got a different design and a different focus. It's a bit utilitarian, but you get a lot of information at a glance -- word and scene counts, scene POV, characters, locations, items in a scene and more. It also lets you open up an unlimited number of scenes at the same time, each with their own window. The only real downsides to me are the lack of grammar checking (really there's not an out of the box solution easily added to projects that I know of), it's Windows only, and it uses an outdated .NET UI framework which means it looks dated and doesn't support dark mode.
Regardless, if you really go looking there are about as many tools trying to aid writers under the sun as there are writers. These have different focuses. I highly encourage you to download and try out multiple tools to see if any of them aid you in the writing process. Personally, I am sticking with a combination of Word and LibreOffice Writer these days. Licensing is a lot less of a headache across different operating systems with Word, and LibreOffice covers the times I either don't have enough licenses, am too lazy to install Word, or am running Linux.
I've been playing around with my own NextCloud / Collabora Online (which uses LibreOffice) setup lately -- it's like having your own Google Docs.
At the end of the day you can write a novel with a plain text editor (e.g. how many people using LaTeX work), so don't stress on the tools too much.
