Best quad op-mp for triangle wave gen

[kinarfi]

I'm using all of a triangle wave for comparison and need a clean wave form, I'm use two of 4 op-amps in a quad op-amp and would like some recommendations of good op-amp or maybe a better design for a clean wave form. Some examples of what won't work are attached and two good ones and the circuit.
Thanks

I didn't think to put labels in the screen shots, but if you hover your mouse over the upload, it will give the name of the op-amp used.

That's shocking. Where's the noise in every waveform coming from?

Try decoupling (a cap or 2) the reference voltage (the 10k pot output) and the power supply. You could also try a snubber on the output of each opamp. Also, be sure to connect both scope ground leads to the circuit ground.

FYI, The scope is a digital DSO-2150 USB, the slight ripple on the slope of most of the waves is because of the scope, I believe, and I also believe the nasty spike at the peaks is just the op-amp design. I used the exact same parts on each screen print, just swapping op-amp in a socket. The TLC2274CN is what I'm going to use so far at $1.68 each.
