Actually Depending on what your making, a TL074 or TL084 might be better These are also Quad op-amps and +/- supplies like the 741.
The 3900 and 324 are single supply with quite low slew rates.
------------------------------------
tlo74 and tlo84 are better chips then 741
chips alone wont produce a better design
the design primarily depends on the experience of the designer
since the person is experimenting 741 is the perfect choice
