What do you expect from a "Diff-OPAmp" that a "Standard Op-Amp" can't
deliver?

For a single 5V supply, I would suggest the LM358 (cheapest, dual,
bipolar, proper output loading needed to avoid dead zone), the MC33078
(low noise, low distortion, dual, bipolar, the ON chips require 10V,
the
ST chips only 5V), the TLC271 or TS271 (single, CMOS, largely but not
fully equivalent, one by ON the other by ST), or the TLC2272 (dual,
rail-to-rail output, CMOS).

Best regards,

Martin.
