It depends on the country I guess. In Spain I never saw a person using Texas Instruments calculators. Casio and HP are way more popular.

We had both depending on the school and sometimes even the teacher. fx-9750G and GII didn't support assembly programming... unless you used an undocumented procedure to flash them with unsupported firmware from a different calculator model...
and nobody enforces a calculator model
We were specifically told to buy TI-84 Plus. Also, there was a list of specific brands and specific models that were approved for use on math exams.
If someone wanted to use a Casio instead, they could. But the teachers also said that if you buy a different brand and model other than TI-84 Plus, you are on your own to figure out how to use it for all the different things we needed graphing calculators for.
Everyone in my class did the sensible thing given that they told us this, and bought the TI-84 Plus. There was no reason to buy a different one when our classes assumed the TI-84 Plus. Only making extra problems for oneself.
