Ok, so now i'll say it. Cubase 7 works (to quote Larry David) "pretty, pretty good." It's much more than that. It's downright slick in so many ways. I've been working in Logic and Cubase for years. Starting projects in one or the other for various reasons, and keeping both because it's just easier. Each has its strengths and weaknesses.
I create advertising, mostly local these days. I taught a little audio production for advertising and played with most of the apps at the time- staying with these two. Over the years, I have used Logic for radio and TV production for whatever reasons. But I've always preferred Cubase for its sound (32-bt floating point, the reverb, internal plug-ins etc). There have been glitches during certain periods so over time I've swtiched back and forth- and Logic has mostly been the fallback because of its stability. I write and record music, which is for love. I seem to go to Cubase first for my music. 24-bit minimum, 96k these days.
ProTools has been the industry standard for years, and I work in and with "real" studios," and it's always a challenge rather than a normal routine- to track, overdub and mix. I'm in a private studio situation. Without the "real" setup, the hardware I can't justify the expense, as I'm guessing many of the Logic, Cubase, DP, etc., users are. It's been reasonably workable for me and I've constantly upgraded my hardware, the AD, DA, clock, etc. I wonder about how sample rate, the clock, stuff like this affects the system, apps and the OS vis-a-vis Core Audio - as the matrix that distributes the data.
For anyone who's at the point of reconsidering Logic as a DAW, I strongly recommend looking at Cubase 7.
WaveLab 7, by the way, is in my opinion the smartest "mastering" solution. I use quotes because I would never master my own music- Mastering is an art of its own and requires a special room, gear and ears. But for posting an MP3 for radio or a bed for a spot it's really strong, expsiecally since the demise of Peak.
Try Cubase.
