I used sheets because it was portable and flexible, but now I'd almost always just use a db instead.
My main use for excel now is "I need to send data to someone who isn't a programmer" and doing json > CSV conversions to see if my 3000 rows of data from a 3rd party have all the necessary bits.
I really enjoyed spreadsheets before becoming a programmer (I still enjoy them, I just spend less time on them) and basically self taught over the years using Google Sheets.
There are several really useful functions on sheets that simply do not exist in Excel, and there are others that work almost the same but not quite. Having to use Excel drives me insane sometimes because of how clunky it feels.
By contrast, using LibreCalc feels kinda how you'd expect an open source Google Sheets to feel? It's slightly clunkier, but it gets the job done and generally feels better to use than Excel
I was once rejected for being too tall. I'm 1.96m (~6'5") and she was ~ 1.65m (~5'5"), said that she didn't like the thought of having to crane her neck to see my face.
