After going through FL and Ableton, I fell in love with Logic.
Compared to Ableton, Logic does seem pretty linear, but I like that. A lot of my favorite music was made on limited recoding consoles, MPCs, etc. The more traditional style of arranging in Logic actually helps force me to be very deliberate and creative with my writing.
No matter what program you use, learning the key cuts is essential to good writing and workflow. I'm at the point in Logic where I can zoom through big chunks of work just pressing buttons. Makes it feel like a big, visual, flexible MPC with tons of effects, synths, and instruments.
