On the whole, I'm with Beepster, and I'm an old school Sonar user (at least a decade now). Take Layers seldom felt different than using multiple tracks for editing. A lot of times, I'd actually just use multiple tracks for comping instead of layers.
Now, lanes are still FAR from perfect, but after watching one of the videos on comp'ing and getting the tip about using the mute tool plus the Ctrl key to promote a single layer, I'm now enamored with how quickly I can comp a track using lanes. My workflow looks like this:
1. Setup track, loop section, record to new lanes
2. Record as many takes as needed
3. Expand Lanes
4. Solo a lane (use Ctrl+Mute Tool to do this) to find the best take of each section
5. Cilck and drag while holding Ctrl (+Mute tool) to promote the best section of each take - this mutes all the other takes within the selection range so you end up with one active track for that time range
Done. The process of performing the comp literally takes seconds and is a complete no-brainer now.
No splitting up clips and clicking and dragging to move around little bits and pieces from prior takes to "build" a whole new take. No weird leftover clips or empty bits that I don't even remember where they came from. No constantly pressing Q to mute/unmute clips. None of that mess. Just promote the section of each track I want to hear with a single click and drag motion and I'm done.
Also, if you need ZOOM in a lane, click and drag an expanded lane in the Track View and resize it. All the open lanes will resize vertically. Click and drag to shrink it when done.
