For me this really isn't true, I can not understand how people would want to edit on FCPX.. I was coming from fcp7 when starting film school and being forced to edit on X. For years I edited all projects on X being frustrated with every single time.
even though the organisation and all is quite innovative, the edit itself feels not precise at all, all those automatic helpful features feel like you have a person that really wants to help you but isn't very good at it and you get so stressed because you never know what she will do.
Never got around this thing of making a transition and it doing those weird bulbs around your take that you can't really move anymore.
And then AUDIO ?? how can you edit fiction film with it, if every audio clip has to get attached to an imageclip, and if you have a coherent sound and you want to change the image above you're really stuck. So many times stuff got desynched because of those mechanisms.. I ended up always using the grey fill in clip on the first level to gain a minimum of flexibility.
Finally, after film school I opened Premiere and found the pleasure and precision I was used to years ago in FCP 7. I could edit without stress knowing that everything depended on where I would decide stuff to happen and nothing would happen just because de NLE thought that it would be helpful
