Is Bucketeer a Cyberduck alternative on the Mac?

For object storage, yes. Bucketeer connects to S3, S3-compatible services and Azure Blob Storage like Cyberduck and adds Finder drives and scheduled sync. If you also need FTP, SFTP, WebDAV or Dropbox, Cyberduck covers those and Bucketeer does not.

Can Cyberduck mount a bucket in Finder?

Not Cyberduck itself. Its vendor iterate offers the separate app Mountain Duck for that. Bucketeer has Mount as Drive built in, as part of Bucketeer Pro.

Do both apps support Azure Blob Storage?

Yes. Cyberduck connects to Azure Blob Storage with an account key or SAS, Bucketeer with the storage account name and key.

Bucketeer vs. Cyberduck, S3 and Azure clients for Mac compared

Name: Cyberduck
Author: iterate GmbH

Cyberduck by iterate GmbH is an open-source file browser for Mac and Windows that connects to S3, Azure Blob Storage and many other protocols, from SFTP to Google Drive. Mounting in Finder is a separate product, Mountain Duck. Bucketeer is a Mac-only app for object storage that browses, transfers, mounts and syncs in one app.

The short answer

Choose Cyberduck if you also need FTP, SFTP, WebDAV or consumer clouds such as Dropbox and Google Drive, work on Windows too, or want a command-line tool.
Choose Bucketeer if you work with S3 and Azure buckets on a Mac and want Finder drives, scheduled sync jobs and watch folders in the same app.
Both connect to Amazon S3, S3-compatible services and Azure Blob Storage, both edit files in other apps and both offer client-side encryption.
