These days I am mostly using online spreadsheets for some of my work. And the collab and share feature is definitely handy with Google sheets. I think at this rate I may move away from both excel online and excel desktop version.
Google seems to be the favorable choice and is one that i used along with google drive, i personally enjoy using my own cloud solution using the Onlyoffice Documents self hosted solution.
overall i prefer google but i do map out my documents on software based excel first then integrate it into cloud unless i specifically need cloud.
