Totally different for me:

• NC-calendar syncs two different calendars (work and private) accross all my devices.
• NC Photos with Memories organizes 2 TB of photos and has all the functions Immich has.
• NC Password Manager syncs my Passwords
• I share big files with my clients via NC and photo albums to friends and family.
• NC syncs and organizes different Input-folders for my paperless-ngx-server.
• I update NC with a small script, works every time

So it replaces at least 5 different Programs. And it’s 80 % private use, 20 % for my business. Not too big, not too clunky, just the right tool.
