Alternative to Onedrive and Google Drive

Does anybody have any suggestions for alternatives to Onedrive or Google Drive? I've been a Onedrive user for many years, I've got a Microsoft 365 subscription, but recently I've been getting more and more frustrated with changes and different aspects (eg Copilot, updates that somehow make everything worse) so looking at possible changes, but I also don't really want to move over to Google 'cause I'm not the biggest fan of Google products either.

Also if you have any suggestions for general alternatives for anything other than Microsoft 365 as a whole (cloud back up, office programs etc, even email) I'm all ears and open to suggestions.

Update to add more info: I only really use Onedrive and 365 as a whole mostly because I've just always used them, so I've never really ventured out into anything different, but I keep getting more and more annoyed with different aspects, so I figured it makes sense to have a look at what is out there. I like that having 365 means that I have everything all together and I can just subscribe all together (Onedrive, Outlook, Word Excel and occasionally Powerpoint), but I'm willing to diversify if there are better products out there, which I'm sure there are.

I would say I don't have too many needs, but I currently pay for 2tb Onedrive space. I like the desktop folder access (idk what else to call it? I like having my Onedrive files accessible on my browser and on my desktop too) but not having that isn't a deal breaker. I'm a PhD student and writer so I mostly use Word for that, and I'm a planner so I use excel, but I'm open to any and all suggestions from people likely far more knowledgable than me.

Also, I'm not super tech savvy, but I wouldn't call myself a complete beginner either, most of what I know comes from searching around, and from being the go-to tech person for my family lol
