I am trying to figure out what the top of the line Sharp non-programmable non-graphing scientific calculator is so I can compare it with the Hewlett Packard HP-35S, Casio fx-991EX and Texas Instruments TI-36X Pro.

It appears the EL-506T is newer, though I can't say what the difference is between them.

The Sharp website lists the EL-W506T and not the 516, and is current as of September '19
