Logic X is actually a terrific DAW, and it’s lighter on resources then Cubase on my machine. Nice bounce in place function built right in. ES2 still sounds fantastic. Logic is a solid choice.
However, I’ve always been frustrated with the mixer and routing in Logic. Audio and midi editing in Cubase are still way ahead of Logic. Cubase just seems more intuitive to me. And I still like the Cubase GUI better, even over LPX.
I can make music in either DAW, but I just prefer working in Cubase.
