I can't think of one. The design is 56 years old. It has its own
Wikipedia page.

There are faster, cheaper, lower noise, lower bias current/offset RRIO
amps around these days.

I remember the day when, still a kid in college, I decided to replace
LM709s with LM741s in a control system. The 741s were more expensive
(the cost of a pretty good lunch) but didn't need external
compensation parts or front-end-zener protection, and current limited.

The early 741s had bad popcorn noise, but I'd expect that to be better
now.

My default gumdrop amp is OPA197 now, in SOT23. It makes a good
comparator too. There are cheaper parts if you can tolerate low supply
voltages.
