I've been using CyberDuck mostly. It'll let you directly edit files if you need to, doing cmd + down arrow will navigate you into the directory instead of attempting to download the entire directory like it does on FileZilla so it's more consistent with navigating in finder
I've never used Transmit, how does it compare to CyberDuck? That's been my go to on MacOS, usually use WinSCP if I'm unfortunate enough to be doing something on Windows for some reason
I played around with CyberDuck and I just never really got to where I liked it... honestly didn't try it out that long as the version I had did not have split screen, which was a requirement for me.
I also like the Transmit Disk function.
FTP folder Sync, Amazon S3 support, WebDAV support, reliable multiple connection support (gives typically higher speed), good built in editor, mount "Favorite" (which is a connection definition) as a disk... those are just a few off the top of my head.
If you just need very simple FTP type ability, CrapZilla is fine I guess, but I've had issues in the past with it and got torqued enough at it I simply purchased what several Mac developers I know recommended.
