A lot of assumptions, half-truths and plain false info come up in all Logic vs. Pro Tools discussions I've witnessed, but there's nothing trivial about a discussion comparing two applications like PT and Logic as such.
Logic and Pro Tools HD constantly are being compared nowadays. It's currently between Logic 8.02 and Pro Tools 7.4.2, and will soon be between Pro Tools 8 vs Logic 8.* (unless Apple develops something completely new).
When two DAWs starting at respectively $500 list and $8,000 list (or is the PTHD list $9,000 now?) are being compared so intensively, - it has a reason, and IMO it's highly relevant to compare the value of PTHD with the increasing 'pro-ness' of Logic.
On one hand, some PT users seem to firmly insist that what we know has happened with Avid vs Final Cut Pro never will happen with Pro Tools vs Logic, while others are attracted to Logic based on that Apple actually both controls the hardware, the OS and the DAW development. Unlike some others, I'm personally 100% convinced that Logic is still being developed - even if there haven't been any sub-releases for quite some time.
Discussions normally both start and end end up with some people preferring Logic while others prefer Pro Tools. Having followed such discussions both in magazines, among colleagues and if various forums for some years, the tendency has been very clear lately: more people tend to want to move from PT to Logic than ever, which eg. this
Pro Tools/Logic poll shows.
It's only fair that some people prefer PT over Logic - and vice versa - but so much happens with the development of Intel chips, with Snow Leopard, 12-core Macs, use of graphics cards to process non-graphical stuff, with Logic itself and with audio optimizations in OSX in general that even if I would have owned a PT based, and not a Logic based recording studio, I'd definitely install Logic even if it was only to be compatible with clients using Logic.
More and more people are relying solely on native processing these days, and nothing suggests that this will change back to mainly be relying on DSP cards - ever. Especially now when we have the global financial situation we have and also know how the situation in the music/recording business has been developing for a while, a switch to more - and not less - use of dedicated DSP cards isn't only unlikely, it just won't happen (unless something very unexpected happens, like eg. that dedicated DSP cards will drop massively in price or that revolutionary features will pop up that just require a lot more DSP power than DAWs usually need today).
"'It is really, increasingly, financial suicide to consider using Avid,' when the same work can be done with Apple gear, he says," Barron's reports. "Alpert's color-correction expert, who 'swore he'd never switch to Apple,' this year made the transition to Apple's program, dubbed 'Color,' with relative ease and is now 'quite happy.' Worse, film and TV's next generation is growing up on Apple's cheaper platform."
Barron's reports, "Avid still has fans, but the devotion gap, if you will, has narrowed substantially with Apple. A recent survey conducted by Piper's Olson of 112 post-production video specialists found 45% using Avid machines and 41% using Apple, with the latter having jumped from 32% just a year ago."
