hay thats not correct dude. both of them gives same precition. only thing is that u get it fast n easy in fls piano roll but cubase piano roll is not as good as fls. cos u gotta select arrow to move it up n to draw u have to take pen tool again. i hate that.
the difference between cubase n fl is like difference between car n a bike. like if u want to reach home u can use any one of them. if u use the car u will have some extra features inside the car which is not necessary for reaching ur destination. if u take bike u will not have that much of features which a car gives . but ur bike has the things to take u home so faster n easier through traffic. anyway in the end u will reach home.
like this cubase got some extra features which only effects the way u work nothing else. eg. 5.1 channel bus, marker tracks, grup tracks, folder tracks etc.
Ableton is a different stuff indeed.very nice. very good lessons, easy to learn n it got one synth called operator which is good for making pads n strings. n ofcource its very fun to use for live playings.
i think the problem u have with exporting in fl loop is bcos its need a good mastering
