Just bought a PreSonus FireStudio Project. it came with Cubase but i also have a copy of apple logic. i'm a mac guy. what would run fastest and smoothest.
It's less a problem with what runs with less latency...it's more about what has the features you want or what you are most familiar with.
If you're a mac guy, then use Logic, especially if you are familiar with it.
There is poetry in despair.
