FWIW, they have added a lot of missing shortcuts in the last few years. Haven't used Windows Excel in ages, though, so I'm not sure what's still missing. That being said, Excel for Mac has gotten slower in a recent update. And the UI text, which already kinda looked crummy and not very Mac-like, now looks even less Mac-like.

But Excel is the lingua franca of business, so I keep on using it.

I haven’t researched recently, but Excel used to run on a single core on the Mac. So any decent sized file would cause tremendous issues. I used to run Windows via Parallels just to use the Windows version of Excel.
