Jochen: Good question. For me, the attraction in Live is that it never stops. (Even if the computer crashes, Live boots right back up where you left off.) The right brain/left-brain division between performing and editing largely disappears because you can edit while you're cruising along. It's the first program in years that has kept me up all night playing happily.
I also like that Live is more streamlined than traditional sequencers, though I do miss the MIDI editing on them. Perhaps that's been why most of the music I've produced in Live has been loop-based.
For the type of podcasts I do, with numerous overlapping sound bites, something like MixMeister might work faster. I tried that on Episode 6.
