How long has it been since you've used LibreOffice?

If lacking a ribbon interface makes you feel like someone chopped off your hands...take your hands off the mouse and put them on the keyboard, haha

I try them at least once or twice a year and always get to the point where I'm like: "Ok, where's my Excel". It's not the ribbon, it's the whole experience that is lacking. Also MS office products do integrate well with each other.

Have you tried SoftMaker FreeOffice? It's not libre, but I've heard good things about it.
