This was done a few years ago at Qld Astrofest and several people took part in an A/B test, it was that obvious.
After imaging many, many thousands of galaxies with both standard LX200 SC optics until 2008 and ACF optics since again a show a very obvious marked improvement in image quality.
The ACF optics outperform the standard SC optics full stop.

I recently had the 10" ACF, 9.25" Edge HD and a LX200 12" in my backyard all setup at once and yes, the difference between the ACF and LX200 12" was quite remarkable. The ACF also looked slightly better than the EDGE HD, but then it had the aperture advantage and there wasn't much in it.
So yes, I would agree, the new class of 'flat' SCTs from Celestron and Meade seem to give *much* better views than the older standard models. I'd get an ACF or EdgeHD if you can afford either of them over a standard SCT.
