I have one Atlas Code 100 Customline turnout, a #6, and I can't say I'm very fussy about it. Aside from the black plastic frog, it seems prone to throwing some of my engines. I thought I had got rid of that problem when I stopped using EZ-Track long turnouts in 2005.
I currently use 5 #7.5 curved turnouts from Walthers/Shinohara. I can't say they are great turnouts. They cause shorts with standard HO tires on powered axles, such as on my steamers if there is a bit of overhang. I have had to cut gaps in one of the closure rails on all of them, just outside of the black plastic spacer. I also have a single #8 of the same kind, and its frog makes the passing items buck much of the time. Some items transit it smoothly. Quality-wise, I'd say they are quite good.
In my yard and on one switchback, I use Peco Streamline Code 83 #6 turnouts. They are excellent, conforming to the N. American format with a straight path through and beyond the frog in each route. The odd short problem, though, for the same reasons as above.
By far my best turnouts, completely trouble-free, and a joy to see in service because of their close tolerances in the frog, are my Fast Tracks handlaid #8's on the main. I will be building my own turnouts from now on. They are worth the trouble for the superior frogs.
