I use both apps frequently. Each for different purposes. I am a creature of habit, so I haven’t experimented much lately, but here’s my take, for what it’s worth.
I do a fair amount of video editing and audio mixing for video projects. I find the editing and track management capabilities of ProTools to be really well-suited for the work. I’m very comfortable with the interface and can work quickly.
I have used Logic for years when composing and mixing music, and love it for that. However, it is rare when I use it for audio editing for video projects. I don’t think it is as user-friendly for that purpose as ProTools is.
When it comes to arranging, mixing and mastering, I think Logic is excellent. Especially with regard to automation. The ability to automate just about any parameter of any plugin or track - and the user-friendly, straightforward way you’re able to do so, is probably my favorite thing about Logic. The only issue I ever have has nothing to do with Logic itself, and more to do with my particular system. In terms of CPU power and RAM, I could stand to upgrade. I often need to be creative when I’m working with sessions that have lots of tracks, and will need to bounce midi tracks of resource-hungry VST’s to audio tracks in order to free up resources. This isn’t necessarily a bad thing, because it forces me to commit to things and not take an eternity to finish something because there are too many available choices.
