After recently trying MuseScore (crude, but functional) and Dorico (awesome, but overkill for me), I settled on Notion. It has a simple and clean interface and does everything a non-professional like me needs. It also has two-way integration with the Studio One DAW that works very well.
On another note, rumor has it that Steinberg will put Dorico on sale by the end of May as part of its 50-year anniversary.
