i use TL071, TL072, or TL074 (single,dual, quad) for most applications. the National Semiconductor LF353 is almost identical in performance to the TL072. i use TL062 and TL064 for battery power applications like guitar effects boxes. for applications requiring higher bandwidth TI has come up with a new higher performance series TLE2072, which is essentially an upgraded version of the TL072. the TL07x series of op amps are low noise, have a GBW of 3Mhz, have very low input offset voltages, and very low input bias currents, as AG mentioned, they have a full output bandwidth of 100khz. and they can operate at up to +/-18V rail voltages. and previously in this thread, we were talking about slew rate.... the slew rate of the TL07x series is 13V/μS compared to the 741's 0.5V/μS. and the supply current is 1.4mA/amplifier which is a lot lower than the 8mA for NE5532 op amps (which means you can operate a lot more TL072's on a 1A supply than you can NE5532's).
