It is more cumbersome to use for MIDI (but more fluent for everything else, IMO), is more expensive and does not have a lot of plug-ins by default that Logic X will have. Pro Tools does hardly give two poops about MIDI and MIDI programming since it is not specialized in that area but it does support every feature that Logic has. You can basically create a prog rock epos in 3 minutes in that DAW if become familiar with all the MIDI tools. If you're using MIDI and synths, use Logic.

If you're a one man army working at home, Logic is probably better for you. It comes loaded with MIDI instrument profiles, samples, loops, drum machines and sounds. Logic and especially Logic X, is marketed to the home producer. It is a software designed for professional audio in every circumstance (film, live, studio, broadcast, etc.)

Pro Tools is better for editing, hands down.
