I've tried OnlyOffice for personal use and it's just okay. There are some things that I consider basic that I tried to do and either they didn't work or it got super slow/laggy/crashed.

This is a good suggestion which could work in some cases for sure.
My answer isn't going to be helpful, because I can't remember specifically what I was doing, but even for a small personal project a year ago, I tried to do something I consider basic, and OnlyOffice (what I was trying out at the time) couldn't handle it and was ridiculously slow.
Are there any actually good replacements for Excel? As an intermediate/advanced user, every alternative I've tried to date pales in comparison. I can't see anyone in my industry switching away from MS because of this, as things currently stand.
Edit: I didn't expect so many replies. I use Sync (I know, it sucks and is dead) and it didn't inform me I had replies, so I'm only just seeing them, apologies. Can't get to everyone though.
For those who think we're using Excel as a database, not really. Can't get into specifics regarding industry, but personally I use Excel daily for a variety of things, none of which is data entry. I build stuff to help calculate and solve issues; I'm not following a specific process in most scenarios. 🤷
Just want to point out that he used the N word once, got hugely criticised for it, and didn't do it again.
Not trying to defend nor minimise any of his actions, btw. Take from that as you will. Just want to clarify, as in my opinion your wording kind of implies he did it regularly.
Most of my ebooks are large as they are comics. You also have EPUB3 ebooks now, which can contain images and audio in them too (think combined ebook + audiobook). So they can get pretty large.
... comics and manga, which is another aspect I've been noticing calibre does not do such a great job
Absolutely. Calibre is horrible with anything that is fixed format. I recently backed up my entire Kindle library with about 1k manga volumes, expecting to be able to convert from KFX to EPUB format as I have been doing for my regular books for 15+ years. Calibre failed awfully at this. The only thing it's reasonably good at with comics, is converting to ZIP format. So I had to write a Python script to take the KFX -> ZIP outputs from Calibre and convert them into working EPUB files.
I'm not talking about uses of Excel as a serious database, though. 🤷
