The LF411 is nice and a modern design, so there have been incremental improvements.



The LF411 is more than 30years old and can be understood as an upgrade to the jellybean 741, but that one is quite shoddy by today's standards. With the JFET inputs and corresponding low bias current, it comes much closer to the ideal OpAmp than a 741, but there's little else speaking for it (well, it's cheap too). LT1028 OTOH is still the OpAmp with the lowest voltage noise afaik (which it buys with fairly high input currents and input current noise), it's still available, but it ain't cheap.

There has been progress in other regards (lower supply voltages, lower power consumption, rail-to-rail operation, smaller packages), but clearly progress in the analog realm over the last forty years has been much more modest than in the digital.
