I did a lot of comparisons over the last couple of years, and kept coming back to the Meier Crossfeed component. I like its simplicity, and it sounds the best to me. I asked Case (the developer) over at the FBK2 forum on Hydrogen Audio if he'd make a new version with greater control, and the possibility of a VST plugin version, and lo and behold, last week they both appeared.
The old Meier Crossfeed had settings from 1 to 10, and I found anything over 2 or 3 too much. The more I used it and A/Bed with the dry signal, the more careful I was with the settings, until I finally settled on 1 for modern electronic music, where a bit of extra width was nice, and 2 for everything else, acoustic, Jazz, Rock, Classical etc., where I preferred the more natural presentation. But I was always wishing to be able to try a position between 1 and 2. And with the new version, we now have it, with 100 divisions, instead of just 10. I find myself using settings from around 15-18 a lot now.
Definitely worth grabbing the new version if you haven't tried it yet!
The VST version also seems to be working great. More info here:
