Data sheets are one thing. Real world performance is another. Graphics cards and CPUs have benchmark comparison sites, but we humble analog circuit people don't have an equivalent. Therefore, it can be a bit difficult for an enthusiast to pick a part that matches aproblem.
So I've decided to try and help a bit. And to get things started, a shootout between 5 (6, really) different quad op amps - all of whom are very affordable and useful in DIY projects as well as "professional stuff" - I've seen quite a few of them in various products, anyway!
The shootout covers a classic oscillator application - a triangle/square output, two-opamp oscillator circuit.

The tested opamps are,
LM2902 (LM324, very similar to LM358) from two different manufacturers. And yes, the manufacturer seems to matter.
TL074 (similar to the TL06x, TL08x) - this particular part is from 1985. Older than me. Blimey!
LF347 (similar to the TL074, but higher bandwidth)
TL974 - a high-bandwidth (12-28MHz depending on supply voltage) low-noise bipolar amplifier.
TLV2372 - a rail-to-rail in/out CMOS op amp.
I was definitely surprised by the results - you might be, too.
TL;DR - the LF347, which is one of the cheapest opamps on test performs all-round best. The TL974 is fastest as expected, but with funny artifacts.
The TLV2372 disappoints, and the LM2902 is as horrible as you'd expect - but it differs between manufacturers.
I'd love to do more of this kind of stuff - so if you're interested in anything like this, say so!
