FL Studio has a nice learning curve too, though different. FL's best features IMO are the pattern sequencer and the piano roll. So intuitive, once you get the DAWs flow you just get creative and the limits disappear.
I moved from Cubase to FL two years ago. I'm in love with the patterns in FL!
The only thing I really miss was the feature in Cubase where you could add effects to an audio pattern in a destructive way. You could create really complex and glitchy patterns and it was easy to mix them together (cross fade and such).
The other thing I would love ImageLine to do is a better workflow when you use audio samples directly in the sequencer. Things like fade in and fade out and a much bigger zoom overall in the sequencer to move samples around.
Edit : I know you can work with Edison but it isn't intuitive imo
