Haven't run them side by side but my feeling is that the ATX easily wins out in contrast at the long end and also has more pleasing OOF highlights. The ATX is most likely a bit sharper too. The F was however run wide open, or nearly so, the whole time. With that taken into account it did a pretty good job. I'll try to get a comparison between them and post some pics. I can't post these because of the private nature of the event.
