"What would it do for me that a 1.25" with the same focal length wouldn't?"

Essentially you get a lot wider field of view from a 2" 70/80 degree ep.

Try https://astronomy.tools/calculators/field_of_view/, and plug in your scope and try different ep's. A 1.25" 30/32mm plossl versus the 2" wide fields at 70/80 degrees.
