I agree that take lanes are just an improvement over the layers mess from earlier versions.
They are easier to mute & solo, and rearrange them into any order you want,.
Things that are possible with takes that aren't with layers include adding written notes to each take, isolate differnet data in each lane, and recording directly to a chosen lane.
Downside is they can take more real estate but even that's neglible, certainly worth it for all the advantages. IMHO of course YMMV and other disclaimers apply......
Best of all they don't have the rebuild function.....
