At that time I don't think I was using either spreadsheet program at a level where I would have needed advanced features. I remember using both, and looking now at old screenshots of the splash screens, I think we did eventually upgrade to SuperCalc 4, probably because of better 1-2-3 compatibility.

There was a "red carpet area" in the office where the high-ups worked, and I remember they all used 1-2-3 and we had to support them sometimes... But we pions were using SuperCalc. More than that I don't remember, it's just been too long.
