I haven't used OneDrive but the iCloud Drive and Google Drive clients are similarly terrible. I one time had 5 GB of complex nested file structure in iCloud Drive and it totally froze up. I tried 2 different Mac's, an iPhone, and an iPad and none of them were able to sync up with the server to get those 5 GB out of the cloud. I had to request a GDPR to get a .zip file of my data... this was the impetus for me to switch to Dropbox although after the way they handled their layoffs I am looking to switch to Syncthing as soon as I have the time to set it up and get familiar.
