Casio or Texas Instruements?

Who makes the superior calculator?

I think the question should be:What calculator can display 999999999 * 999999999 better?I wouldn't know. Why would I spend 200$ on two calculators that do the same thing?I use texas instrument because it's a calculator.

I had a casio since my school recommended that particular one.

i only know casio texas never heard of is it an international company?
