FLStudio is just as powerful as any other DAW (Logic, Reason, Ableton, etc.). However, a lot of people don't know this because of its reputation; since FLStudio offers a very user-friendly interface, it is much easier to learn with, grow with, and understand on than it is with a lot of other professional DAW programs. Its user-friendly interface is probably what attracted all the turds who pirated it illegally and made all those horrible songs which were then uploaded to the internet in numbers so massive you'd think it was ****ing a smallpox outbreak or some shit. Thanks to them, this is why FLStudio is looked down upon as an amateur, obsolete program.
Don't buy into the propaganda though, folks. The fact still remains the same: the end product is merely a reflection of the artist's overall producing + mixing abilities. If you know how to use FLStudio the right way, then you know how to make a track sound like any other track from any other DAW. It's really a matter of how good the producer is.. because seriously, the program has practically everything you need.
Also, as of right now, FLStudio is releasing more additional features, more new synths, effects, etc on a rate faster than any other product. It has come a really long way and it is looking fan-freakin'-tastic at this very moment.
