Do not know about Final Cut (it's well optimized for Silicon by the way), but Logic Pro is definitely one of the music industry standards.

Since other semiconductors like Germanium aren't used to build CPUs, I would argue all current software is optimized for Silicon?

SCNR...

What is? Adobe? Davinci? My assumption was also that Final Cut Pro was _the_ one.

FCP 7 was dominant but the disaster of early versions of FCP X forced a bunch of shops to switch to Premiere.

There are still things that make Premiere better. Recently I couldn't get an mp4 from a Sony cam to play at the right speed in FCP no matter what I tried, and it just worked in Premiere. I'm more fluid in FCP but I will probably switch too as Premiere just "feels more pro" now to me.

I've heard some great reports about Davinci, especially for post.

Most big-budget feature films are cut on Avid and that's been the case for a while now; for indies my impression is that it's 50/50 Premiere and Resolve, yup.
