Fl Studio Pros:
-Easier to jump into and just make something
-Has a unique fun factor to it
-Sampler channel is easy to instantiate and use
-Cool built in synths, especially for current dance music (even older)
-Great modular tools for creative routing/sound design
-Clips/patterns freely movable to any track (The instrument and/or effects follow the clip.)
FL Studio Cons:
-Not great at multi-track at recording.
-Recording audio general is a bit quirky
-Have to route all instruments and audio manually to mixer
-No way to save patterns w/ instrument and effects
-No Freezing (even though they claim)
-Bouncing is long winded compared to Logic
-Bigger projects and easily turn into chaos and confusion, (no track folders, hidden automation lanes. You can make things smaller, but you're unable to hide.)

Logic X Pros:
-Interface very easy on the eyes.
-Arguably the best included Instruments,Loops, and samples of all DAWs
-Deep midi functions
-Apple Loops! (You can save clips that allow you to reload the instrument with midi and effects)
-Much easier to stay organized (Folders and Sub folders for tracks)
-Multi track recording is a breeze.
-Comping Audio/Midi
-Track Freeze
-Bounce in place much easier than FL
-Tracks already routed to mixer
Logic X Cons:
-Not as easy to jump into and make something
-Automation is pain to add if going through the drop down menus (There is a work around using touch or latch mode.)
-May not have as much of a fun factor as FL <-Subjective
-Modular routing is way more daunting than FL
-Clips/Regions are not freely movable to any track. (Only audio to audio / Midi to Midi / Automation to Automation. Instrument and/or effects don't follow the clip)
EDIT: Just noticed OP is from 5 months ago lol. He / she has probably moved on by now. I'll leave this up for folks with the same sorts of questions in the future.
