> Excel is the best spreadsheet software in my experience when you have to move beyond the basics. I’ve even tried hard to use the open/Libre alternatives.

I strongly agree, but even for the basics! I use LibreOffice for personal use and put up with it only because it’s not Microsoft. It’s laggy, copy paste sometimes doesn’t work, the user interface is quite dated, the fonts are ugly…the list goes on. I donate to Document Foundation so that it can get better, but it moves very slowly.
