I tend to be Cubase only at home, Pro Tools is still somewhat clunky with its MIDI capabilities and displays, etc., and if I work with someone with Pro Tools, I just get them to send me a stem and then simply send them back stems of my parts.
ProTools is a VERY good audio DAW, but Cubase started as a MIDI app, then added audio. ProTools started as an audio DAW, then added MIDI!
But at $200, Logic doesn't seem too expensive to simply try for a while. But I'd have to update my entire OS, as I'm still on 10.6 Snow Leopard.
