I'm a big Cubase SX2 fan, but I use FL Studio for writing techno for the sake of one feature - the step editor. SX has a step pattern sequencer too I know, but it's not nearly as productive as Fruitys for programming pattern based stuff :( I really dislike Fruity's interface though and I wish to all hell Steinberg would address the issue properly so that I could ditch FL... Oh, and they could throw in a decent soft sampler too :P FL's isn't wonderful, but it's better than Halion IMO (and you have to buy that separately).
