I don't use logic. I find it to be no good but regardless I still wouldn't die on that hill.
There's many things I disliked about logic when I tried it and that led to my opinion on its only useful for music production, I would probably not even say editing...
More on the composition level. If I'm tracking it's into Pro Tools, any edits happen there too. I personally don't move out but other's do really prefer to do more production work in Logic so I would happily bounce out tracks for them. Ironically AAF would solve that problem too...
Regarding cuts on zero... I basically never do so all my cuts will have a crossfade, generally the real world is just a little too chaotic to have a zero crossing just about where I would prefer the cut...
