Final Draft has been around for so long that it's just the de facto screenplay tool by this point. It's easy to get started with and it has all the fundamentals you'd expect.

I like the most how simple the program is. It is super easy to use, you can use it on two devices so your laptop and computer. I have been using it for like a year now and I only can recommend it. You can export and change the first page, revise mode is useful too.

The easy format it always gives me. I’m able to work knowing Final Draft is the standard for writing and exceeds all expectations.
