There have of course been several "favourite calculator" threads over the years, but I will try to give an answer that fits inside this topic :-)

If I would have to choose a single favorite calculator it will always be the Ti 59. Because of my personal attachment to this calculator: It helped me through my final year at school (where I was in the mathematical/natural science section) and through university (aerospace eng.). These were the years when I really needed a calculator and the Ti59 was the only affordable one that could do everything that was required then. All HP calculators of the late 1970ies/early 1980ies were insanely expensive in my part of the world, and could not do anything that a Ti 59 wasn't also capable of. Mine still works nicely after 40 years, so build quality of Ti can't have been as bad as one often reads on the internet. At least not for the high-end models. And I also like Ti's algebraic entry logic very much. I was never afraid of ( ) and = keys.

And regarding the topic: With it's normal inbuilt statistics functions the Ti 59 did not store data pairs. It used summation based statistics instead like most calculators now and then. Using the "Applied Statistics Module" of 1977 a Ti 59 could store up to 69 data points (according to the manual available for download at datamath.org - I can not verify this because I don't have the module).

Could I choose five favorite calculators instead (from my collection - there may be others that I don't have seen yet) these would be, in no specific order:
Ti 59
HP-25
Aristo M27
HP-71B
Ti Voyage 200
