I converted to Apple Numbers about a year after it came out, and both Excel and Google Sheets seem completely archaic to me now. I've sent PDFs of my Numbers docs to people and they are blown away. Now that I can share Numbers through iCloud to both Mac and Windows users, I've got some people fully converted over.

Excel is great as long as you stick to the basic use cases. Start going nuts and it gets really slow. I think Apple got it right when they made their spreadsheet app have a much smaller table so people don’t try to use it for massive things

Also you can't open two Excel files with the same name.
